摘要： An excitation circuit for a flux switching motor. The circuit includes a low-value film capacitor across the DC side of a bridge rectifier. A plurality of electronic switches are arranged in an H-bridge configuration for switching current flow through an armature winding of the motor in accordance with a PWM control scheme and single-pulse control scheme controlled by a microcontroller. A start-up diode is placed across the field winding of the motor and is electronically switched out of the circuit after a startup phase of the motor has completed. The circuit implements armature energy recirculation through the field winding during startup to promote more uniform and quicker startup of the motor. The use of a film capacitor improves the power factor of the circuit, helps to eliminate the introduction of harmonics into the AC voltage source, and helps in mitigating EMI. Reverse commutation is used to bring the motor to a quick stop when it is powered off.

摘要： A method for controlling a multi -phase motor includes withholding energization of a first phase of the motor for a non-zero period when the first phase's dwell time begins. Energization of the first phase is activated upon the expiration of the non-zero period. Energization of the first phase is deactivated for the remainder of the dwell time at a deactivation time occurring before or at the expiration of the dwell time.

摘要： The invention relates to a method for controlling a reluctance motor which comprises a rotor and a stator. The rotor comprises a plurality of rotor segments and the stator comprises a number which are independent from the coils, for example, six rotor segments for eight coils. The invention also relates to a control device which applies tension to a coil of a respective phase of the stator. According to the invention, at the moment when a first coil is excited, i.e. when a rotor segment is displaced towards the coil, the second coil which follows in the rotational direction of the rotor, can also be excited, and the position of the rotor is detected by sensors. The aim of the invention is to produce a method, wherein a reluctance motor can be controlled in an improved manner when running at a very high rotational speed and also when running at a very low rotational speed. According to the invention, the first coil is excited according to a predetermined, modifiable time frame and the subsequent coil is excited in the form of phase overlapping, within a time frame under the proviso that the position of the rotor is determined. Phase overlapping is maintained until the expiration of the time frame.

摘要： An electrical machine is controlled with a combination of a physical rotor position transducer and a software position detection algorithm. The physical transducer has a reduced number of sensors, so that it will only give accurate information at high speeds. The software algorithm is executed by a low-cost processor which cannot provide sufficient information at high speeds. The controller blends the information from the two position detectors to produce an economic drive which operates over a large speed range.
