Application Example For MSK4310 Speed Controller

From M.S. Kennedy Corp.
 

 

The MSK4310 3 Phase DC Brushless Speed Controller hybrid is a complete closed loop velocity mode controller for driving a brushless motor. It requires no external velocity feedback devices for operation. Feedback is derived from the hall signal outputs from the motor.

In velocity control, velocity sensing from the motor is used to create a feedback to signal the controller to either speed up or slow down the motor to match the speed input signal in a control loop. The feedback signal and the input signal are fed into an error amplifier. The output signal of the error amplifier will then supply the proper information to a pulse width modulator (PWM), which will chop the DC supply voltage to the motor. This chopped DC voltage will cause the motor to respond as though it were a smooth, proportional DC voltage that will either speed up, slow down or maintain a set speed, regardless of the load on the motor.
