摘要
A control process for a brushless three phase motor (1) system (10) has an inverter with upper (21-23) and lower (24-26) bridges. One side of the inverter is switched by a signal synchronous with a rotor angle in a 50% cycle ratio and the other side with pulse width modulation when a bridge switch is open. A control process for a brushless three phase motor (1) system (10) has an inverter (20) with three phase bridge arms each with upper (21-23) and lower (24-26) side switches. One side of the inverter is switched by a three phase signal, synchronous with a rotor angle in a cycle ratio of 50%. The other side of each bridge is switched with a pulse width modulation signal during a period in which the switch on the one side of the bridge is not conducting. Independent claims are also included for a control device and for a motor system.
