摘要： A location and retention component is provided for positively locating an overspeed guard and retaining a centrifugal actuator at an optimum positional relationship relative to each other. The system includes a first and second retention element removably engagable to the output shaft of a motor and axially fixable to the shaft at corresponding locations to maintain the optimum positional relationship. The first retention element serves as a positive stop for assembling the overspeed guard on the motor shaft, while the second retention element ensures that the centrifugal actuator is properly placed within the overspeed guard.

摘要： A centrifugal switching device of a single-phase induction motor includes a centrifuge and pressure switches. The centrifuge includes a centrifugal sleeve, a centrifugal base, shaft coupling blocks, and a spring. The spring is directly fitted on the centrifugal base. Under a centrifugal force generated by the rotation of the motor, shaft coupling blocks I and II slide axially against an axial force of the spring, thus forcing an axial end surface of the centrifugal sleeve to be separated from contacts of the pressure switches, such that a starting winding of a stator ferrite-core coil of the single-phase induction motor is disconnected and a heater is turned on. The shaft coupling blocks I and II adopt a design with round transition, central sliding contact, and smooth rotation, thereby achieving a simple structure, convenient mounting, and safety usage.

摘要： A switch lever for use with a centrifugal starting switch of an electric motor. The starting switch has at least one switch contact which is moveable, in response to axial movement of a centrifugal actuator, between a start position in which a starting winding of the motor is energized and a run position in which the starting winding is de-energized. The switch lever of the present invention operatively connects the switch contact with the centrifugal actuator for movement in response thereto. The switch lever has a cam follower at one end which is engageable with an annular actuator collar of the centrifugal actuator. The cam follower includes a contoured rear cam face which prevents the cam follower from becoming "stuck" behind a flat rear surface of the actuator collar during assembly or operation of the motor.

摘要： A D.C. motor includes a brush and commutator used in starting the motor, but which are not used during the running cycle of the motor. The rotor is formed of a permanent magnet. The stator includes a pair of opposite pole driving coils arranged 180.degree. from each other. A sensing coil is placed halfway between the two driving coils. A starting coil is also included halfway between the driving coils and directly across from the sensing coil. Brushes are mounted on the rotor which contact the stationary commutator when the motor is at rest or just starting. As the motor speeds up, the brushes are centrifugally removed from the commutator, thus breaking the starting circuit.

摘要： A synchronous motor comprising a permanent-magnet rotor and a stator which, at startup, uses rectifiers for supplying the stator coil with rectified current and a commutator consisting of sliders and brushes both rotary in union with the rotor in order to supply only the rectified component, effective to energize the rotor's rotation, from the AC power-supply, and which is provided with a mechanical conversion device designed such that, when the rotor's rotation has reached nearly the speed of synchronous rotation, the slider is allowed to move in the direction along the rotary shaft to become released from contact with the brush, for removal of contact load and at the same time to supply the stator directly with the power-supply AC.
