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： An apparatus for controlling the speed of an induction motor includes a first winding and a second winding. The first winding and second winding are adapted to be coupled to an AC source for supplying an AC input signal. A first switching device is coupled to the first winding and a second switching device is coupled to the second winding. Each of the switching devices is operative in a low impedance state enabling current to flow through the associated winding of each switching device and a high impedance state preventing significant current flow through the associated winding of each switching device. A controller switches each of the switching devices from the high impedance state to the low impedance state in a sequence for controlling the current in the windings, which induces a phase shift between the AC voltages across the windings.

摘要： An apparatus and method controls the speed of an AC induction motor by varying the frequency and current to the motor from an inverter power supply. A Counter EMF regulator receives a reference signal corresponding to the desired speed, and a signal proportional to CEMF for feedback. The output of the CEMF regulator is provided to the power supply to control the current to the motor. The CEMF feedback signal is also utilized to vary the output frequency of the power supply in accordance with the magnitude of the CEMF. This maintains the magnetizing component of stator winding current at a constant value for all operating frequencies of the motor. A signal corresponding to the load current component of the stator winding adds to the speed reference signal to the CEMF regulator to increase CEMF and frequency with increasing load, thereby to compensate for increased slip and maintain constant speed. The voltage on a DC bus in the inverter power supply is compared to a reference signal, the magnitude of which corresponds to the voltage on the bus when the motor is operating at synchronous speed. If the bus voltage is less than the reference voltage, the motor is in the motoring condition and the frequency of the power supply is determined by the CEMF. If the bus voltage is greater than the reference voltage, the motor is regenerating, and the frequency of the power supply is increased to prevent regeneration, and to avoid the need for the power supply to absorb regenerative energy.
摘要翻译：装置和方法通过从逆变器电源改变电动机的频率和电流来控制AC感应电动机的速度。反电动势调节器接收对应于期望速度的参考信号，并且与CEMF成比例的信号用于反馈。将CEMF调节器的输出提供给电源以控制电机的电流。 CEMF反馈信号也用于根据CEMF的大小来改变电源的输出频率。这将电机的所有工作频率的定子绕组电流的磁化部件保持在恒定值。与定子绕组的负载电流分量相对应的信号将增加到CEMF调节器的速度参考信号，以增加负载的CEMF和频率，从而补偿增加的滑差并保持恒定的速度。将变频器电源中的直流总线上的电压与参考信号进行比较，参考信号的大小对应于电机以同步速度运行时总线上的电压。如果总线电压小于参考电压，则电机处于运转状态，电源频率由CEMF决定。如果总线电压大于参考电压，则电机正在再生，并且增加电源的频率以防止再生，并避免电源吸收再生能量。
