    摘要: An electrically controlled brake includes a rotatable first mechanical system and a second mechanical system that is stationary or fixed. The two systems have friction surfaces/parts that can be made to come in engagement with each other, providing a braking effect, and be withdrawn from each other releasing the braking effect. In the second system, windings can be wound around two braking shoes made from soft magnetic material so that an electric current flowing in the windings affects magnetic fluxes through the soft magnetic parts to move at least one thereof. The movement is in a direction that affects the effective width of an air gap in the closed main magnetic path. The electric current gives attraction forces over the air gap which tend to move the braking shoes to reduce the length of the air gap. A spring that e.g. can be a flat spring is rigidly mounted to inner ends of the braking shoes, creating forces on the braking shoes acting in a direction substantially opposite that of the attraction forces. The spring and the braking shoes form a unified structure that via a portion of the spring is rigidly attached to a stationary component of the brake, such as through a bar. Since the movements of the braking shoes are not performed about some shaft or articulation, there is no mechanical play in the brake.

    摘要: A fast automated gear shift operation is performed using a powertrain in a hybrid vehicle, the powertrain including a gear box, an engine, at least one controllable motor, a torque ripple damping device, a mechanical connecting device for connecting or disconnecting the engine to or from, respectively, wheels of the vehicle. In the gear shift operation the motor is controlled to perform a sequence of steps in which different torques are delivered by the motor to temporarily change the speed thereof. The torques are selected so that they to reduce the mechanical tension over at least one elastic part of the powertrain. Hence it can be achieved, that during at least a period during the gear shift operation torques over mechanical elements in the gear box cooperating in the current gear and/or over the mechanical connecting device are eliminated or at least strongly reduced. The period should be sufficiently long so as to permit disconnection of said mechanical elements cooperating for the present gear and/or to permit disconnection of the mechanical connection device.

    摘要: An encoder disc (101) of an optical position transducer is mounted on a short protruding part (102a) of a rotor (102) of an electric motor close to torque creating parts. One part of the optical system, normally the light emitter part (108, 115), is insertable between the rotor (102) and the encoder disc (108) after the insertion of the rotor-encoder disc assembly into the motor stator case (113). The optical incremental encoder signals are fed both to a moderate frequency digital counter that counts 4 counts per basic encoder period and to an A/D-converter that samples and digitises the primary encoder analog signals. A synchronising network ensures that the primary encoder digitised signal corresponds to the correct state of the digital counter. More than one decoder head can be used to compensate for the bearing play common in servo motors having varying axial loads. This construction gives a high speed resolution and fast speed response, is very compact and operates with modest demands on bearing precision.

    摘要: High torque brushless motors are proposed which have low weight and high efficiency. The permanent magnet rotor has many equally spaced poles of alternating polarity. The stator has a plurality of pole groups, each pole group have a plurality of poles with the same pitch as the rotor poles. Windings (211-216, 221-226, 231-236, 241-246, 251-256, 261-266) connected to electrical phases (R, S, T) are provided on the poles within each pole group to polarize the poles in the group with alternating polarity. The pole groups are displaced relative to each other and the gaps between the pole groups are filled by flux balancing poles (217, 227, 237, 247, 257, 267) which in many cases are unwound. The motor may be driven by means of an inverter and by providing it with at least two winding sections of each phase, configuration switches to connect the winding sections in at least one serial and one quasi-parallel configuration and at least twice as many bridgelegs (twice as many inverter switching elements) as would otherwise be required as a minimum in the selected bridge configuration it can be driven at two different torques. The configuration switches may be constructed as very low resistance high current mercury switches having a favorable geometric design.

    摘要: A cassette magazine for a component mounting machine. This machine comprises a driving member (34) for a number of reels (7) which are insertable into the magazine and which carry components enclosed in a carrier tape (2) wound on each reel. The reels are arranged in standing position in one or more parallel rows (9,10) transversely to the feeding direction of the tape. The tapes are by means of driving members fed to a component expelling and picking station (23) in which means (24) are arranged to punch the components from the carrier tapes so that they will be accessible for a picking tool. The driving members comprise a number of feeding wheels (32) and drive segments (43) corresponding to the number of tapes, said wheels and said segments being arranged for individual feeding of each of the tapes. The feeding wheels are stationary with respect to the magazine whereas the drive segments are supported on a movable carriage (40) and can be brought into and out of engagement with the corresponding feeding wheel by means of electrical members (44 ). The carriage is displaceable in the transport direction of the carrier tape by an electric motor (35) between two end positions whereby the carriage movement is coordinated with energizing of the electrical members in such a way that a certain feeding wheel and the corresponding drive segment will be brought into engagement with one another for displacing the carriage from a first end position to a second end position and out of engagement with one another when returning the carriage from the second end position to the first one.

    摘要: A position transducer for a rotary member such as the rotor of a motor has a rotating encoder disc and flat, disc-shaped elements interacting with the encoder disc to produce position dependent signals. The encoder disc has at least one active element such as metal surfaces configured so that signals from one of several portions or sectors of the encoder system are not transferred to another portion or sector, thus permitting the position transducer to be split into several position detectors that can operate independently of each other without having signals from one position detector affecting the other position detectors. The position detectors can cover individual circular sectors or concentric rings and e.g. be based on sensing the capacitive coupling between transmitter and sensor electrodes located on opposite sides of the encoder disc. The components of the transducer can be assembled with substantial air gaps between them and be made from materials that are not easily destroyed by corrosion and contaminants like dust particles, water, oil or lubricant grease. The position transducer also permits detecting multiturn rotation without additional mechanical components.

    摘要: An electromagnetic rotary actuator is driven by a single-phase voltage. Permanent magnets on a rotor interact over a part-cylindrical small airgap with a soft-iron stator having pole teeth that carry at least one winding for rotating the rotor within a limited angular range, the airgap having a high flux density. The windings are applied around those of the pole teeth that are centrally located. The permanent magnets and stator poles have the same angular pitch. The actuator is compact having a low total length and has a high output power/loss ratio and allows a fast response. It can be built with a low thermal resistance to an enclosure or casing by having the coils being in direct mechanical contact therewith.

The position transducer provides at least one analog signal that varies periodically with the moving position of the modulating portion, where the movement of the modulating portion has a period. The analog signal is provided to a converter that converts the analog signal into digital information which is applied to a computing arrangement to provide information as to the position of the modulating portion by using at least one transformation including stored information as to deviations of the periodic variation of the analog signal relative to a sinusoidal shape having a constant amplitude for all periods of movement of the modulating portion.

    摘要: A surface mount machine has a fixed X-axis comprising a straight beam rigidly mounted in the machine chassis along which one or several wagons move(s), each one carrying at least one component pick-up device. Below the X-beam for the X-axis there are component feeders which are organized in groups and which are accessible by the pick-up devices and at least two Y-axes provided by linear bearings, which are rigidly mounted in the machine chassis. Y-wagons for carrying printed circuit boards move along the Y-axes. As there are at least two PCB carrying Y-axes, it can be arranged that at least one of them presents a PCB on which the pick-up devices can place components. The time during which the pick-up devices must be idle during PCB unload and load will thereby be dramatically reduced.
