摘要： An electric motor and its controller are specially adapted for variable speed applications. The stator of the motor has its main windings controlled by triacs. The triacs are placed to allow the main windings to operate in series at low speed and in parallel at high speeds. The firing delay of the operating triacs is controlled in both series and parallel winding operations to aid in smooth operation of the motor. The auxiliary winding is preferably left uncontrolled to contribute a regular sinusoidal component to the windings power at all times. The controller receives the speed command and figures firing delay and outputs triac control pulses at one of a plurality of settings to bring the motor to the selected speed. In this manner a simple, inexpensive, and continuously variable speed motor may be realized with good performance characteristics.

摘要： An electrical rotating machine comprises an inverter drive system wherein alternating current comprising more than three phases is produced from the inverter drive system. The machine further includes a stator comprising a plurality of slots and windings, wherein the windings are electrically coupled to the inverter drive system and a winding chording factor of the stator is approximately 1.

摘要： A three-phase a.c. motor for operation with a three-phase mains supply (1), with three single- or multiple-strand windings (2u, 2v, 2w) in a star configuration (2) in which terminals (U2, V2, W2) at the neutral ends of the windings (2u, 2v, 2w) are accessible outside the set of windings (2), with an electronic switch (4) so constructed and so connected by way of switch terminals (U3, V3, W3) to the neutral-end terminals (U2, V2, W2) that the latter can be electrically connected to one another during a process of turning on and disconnected from one another during a process of turning off, and with a control circuit (5) designed to control the electronic switch (4) and connected to the latter. By integration of the electronic switch (4) and the control circuit (5) within the terminal box of the three-phase motor, both the space required and the number of electronic components can be dramatically reduced in comparison to known three-phase motors.
