There are numerous Hoffman EC Motor Controls like refrigeration evaporator fan controller, manual motor speed control with PWM output, ECM two speed comfort control, ECM 4 speed motor control, manual motor speed control, ECM variable speed drive, ECM head pressure control for variable speed EC motors, etc. Now, we have to look at some of the Hoffman ECM Controller. Generally, ECM Controls Hoffman is available in 700 series.

The 760-ECM Series Electronic Motor Speed Controller is designed to provide energy-efficient ECM (brushless dc) motors with manually controlled proportional speed control. This controller requires only a 24 VAC power source and it is independent of line voltage, Motor speed control is performed through a modulated pulse width signal from the ECM which drives the ECM motor through its dedicated control signal input.

By using the built-in tachometer signal, the 763 ECM Controls the speed of variable speed EC motors. Control can be done remotely by using the Modbus RTU interface or locally can be done with the use of LED display and control buttons. So, with this controller, the EC motor speed can be controlled either by manual or automatic.

A speed index (0-100) is used in manual mode to set the control signal to the motor. Both the motor rpm and speed index are displayed on the LED screen and the Modbus. The motor rpm is set directly in automatic mode, and the control uses a PI feedback algorithm to drive the motor rpm to the defined value, independent of loading on the motor, as sensed by the tachometer signal.
