BM64070MUV-E2集成電路（IC）的電機驅(qū)動器控制器規(guī)格書PDF中文資料

General Description

BM64070MUV is the pre-driver IC of sine wave drive

for three-phase brushless motor driver that supports

48 V power supply controlling the motor driver

constructed in external FETs. The sensor-less drive

that the hall devices for the position sensing are

unnecessary is adopted. It has a speed feedback

control function, and controls output PWM Duty by

adjusting the rotational frequency characteristics for

the input PWM signal and the rotational frequency

affected from motor.
