摘要： A teleoperated surgical system includes a manipulator, an electric motor, and a power circuit. The motor is operatively connected to and configured to drive movement of at least a portion of the manipulator. The power circuit includes a plurality of wires and a switch. The wires connect a selectively activated power source to the motor. The switch is connected to the wires between the power source and the motor. On a first condition in which the power source changes from an activated state to a deactivated state, the switch short-circuits the motor to cause the unpowered motor to automatically dampen motion of the at least a portion of the manipulator. On a second condition in which the power source changes from the deactivated state to the activated state, the switch electrically connects the motor to the power source to supply operating power from the power source to the motor via the wires.

摘要： An operation device includes a motor capable of forward and reverse rotation, a transmission mechanism configured to convert forward and reverse rotation of the motor into linear ascending and descending motion and to provide tactile stimulation on an operation unit, and a controller configured to control switching of an energizing direction of the motor. The controller is configured to control acceleration such that an amount of ascending movement of the operation unit is increased by increasing driving power in a forward rotation direction of the motor, and to control deceleration such that the ascending movement of the operation unit decelerates by supplying driving power in a reverse rotation direction of the motor, in a predetermined time from when the operation unit starts the ascending movement via the transmission mechanism until a target displacement amount is reached.

摘要： Method and apparatus for the operation of a direct current (d.c.) motor requiring no start-up resistor and accompanying switches. Regenerative braking is obtained and the torque interference in the operation is carried over to the electrical input after being dampened, due to the "soft" speed/torque characteristic. The d.c. motor is directly controlled by a technique which stimulates either the characteristics of a shunt-wound motor or a series-wound motor. A command signal is provided by an adjustable signal source which is adjusted in accordance with the armature current desired. A d.c. voltage source is controlled to provide an armature current in accordance with the command signal. When the armature voltage reaches its nominal value, a controlled d.c. current source is regulated in accordance with an error signal which is the difference between the command signal and the armature current, to regulate the excitation. The armature current/armature voltage control is thereby switched to an armature current/excitation control under which control the d.c. motor follows the "soft" speed/torque characteristic curve. To achieve braking, the command signal is reversed. This condition is detected by the differential unit to initiate braking. By maintaining the given nominal load current in accordance with the command signal setting of the signal source, motor speed decreases until the excitation reaches its nominal value. This condition is detected, causing the armature current/excitation control to be switched back to the armature current/armature voltage control. With decreasing speed, armature voltage is reduced in value until the d.c. motor stops.

摘要： A PWM speed regulating apparatus for DC elevator comprises a rectifier-filter (1), voltage suppressor (2), chopper voltage regulator (3), system controller (4) and a driving protector (5). The speed of DC motor is regulated by a pulse width modulating mode so that the current of the motor is maintained continuously and the ripple of current and torque is lower, and which ensures a good riding quality and a high floor arrival accuracy.

摘要： A digital current regulator circuit for a DC load that is connected within a transistor bridge circuit for multi-quadrant operation contains a digital comparator to which binary actual value codes and theoretical value codes are applied as well as a control unit for the time-discrete unipolar control of the transistors in dependence on a central timing signal. To avoid current distortions when the polarity of the load current changes, a blocking circuit is provided, by means of which the bridge circuit can be blocked when the polarity of the theoretical value code changes. A release circuit is also provided that terminates the blockage as soon as the load current actually becomes zero.

摘要： A digital current regulator circuit, especially useful for a DC motor, is described which is fed directly, i.e., without power transformers, from the AC mains, via power transistors (T1-T4) that are controlled by pulse modulation and which can work in four-quadrant operation. An A/D converter (12) generates from samples of the motor current, an actual-value signal in the form of a multi-bit parallel binary code; and a binary comparator (20) compares the actual-value code with a theoretical-value code and generates binary error signals if the actual value is greater or less than the theoretical value. To provide DC-isolation of the power transistors and associated circuitry from the control circuitry that generates the error signals, the parallel bits of the actual-value code are transmitted to the control circuitry through an opto-electronic coupler (14). Other opto-electronic couplers (16, 30) can be provided to transmit other control signals.

摘要： A drive for a high-voltage isolating switch includes a shaft which acts on a moving contact of the isolating switch, a flywheel which is connected via a coupling to the shaft, a drive motor for energizing the flywheel before a switching process begins and a control circuit. The control circuit is used for determining the direction of rotation of the drive motor during the energizing process and for automatically switching the drive motor from a motor to a generator operation, during a period when the movable contact is to be moved. The motor is preferably a series-wound motor which provides high operational reliability. A rectifier is connected in the current path between the rotor and stator windings of the motor. The rectifier stabilizes the current direction in the stator winding during the switching-over phase of the drive motor from motor to generator operation.
