#CMT# #/CMT# The motor control device has multiple operating units of inverter type for operation of appropriate phase coils, and has multiple pulse width modulated (PWM) control unit for PWM control of appropriate operating units of inverter type. Each of PWM control unit is configured to implement a switching sequence. The ends of phase coil are subjected in accordance with the operating units with a voltage of a current supply, a condition of the connection of ends of the phase coil with a positive side and negative side of the current supply. #CMT#USE : #/CMT# Motor control device for application of a motor with multiple independent phase coils. #CMT#ADVANTAGE : #/CMT# The multiple pulse width modulated (PWM) control unit are provided for PWM control of appropriate operating units of inverter type, where each of PWM control unit is configured to implement a switching sequence, and hence ensures a limit value defined by different safety standards under safety aspects. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic circuit diagram of a motor control device. (Drawing includes non-English language text). 1A,1B : Phase windings 3A,3B : Drive sections 7A,7B : Current detectors 51 : Amplifier 52 : Comparator. |
