Low standby power loss pattern of the power consumption close to zero, so as to effectively reduce the stand-by power consumption of motor driver.
It should be noted that in the relevant technologies, when motor is controlled to enter low standby power loss pattern, mainly pass through machinery
Formula switchs (e.g., relay) to realize, but since certain motor drivers are mounted in inside motor body, by installation space
With the influence of installation environment (high temperature, magnetic field) so that realize that connecting and disconnecting of the circuit has certain risk by mechanical switch, because
This, in an embodiment of the present invention, by low standby power loss device according to motor speed command signal and predeterminated voltage with reference to letter
Magnitude relationship between number directly controls the voltage break-make between power supply and motor control unit.Further, can lead to
The comparison control unit crossed in low standby power loss device carrys out 31 pairs of motor speed command signals and predeterminated voltage reference signal carries out
Compare, and then the voltage break-make between power supply 10 and motor control unit 20 is directly controlled according to comparison result, compared to
