Electric machine controller |
摘要 |
A controller for a switched electric machine, especially a switched reluctance motor, takes timing information from a rotor position transducer to generate a switch-off output at a point near maximum phase inductance in a phase inductance cycle. A switch-on signal is generated after a delay but still within the phase inductance cycle. A simple form of single-pulse control is thereby achieved. A comparator is also provided which monitors phase winding current. A pulse generator is actuated by the comparator when the winding current exceeds a reference level and is used to control the motor in a chopping mode at low speeds and is disabled by the comparator at higher speeds when the single-pulse control is used. <MATH> |
