F5D4-NM10Y is a type of multi-purpose, 3-phase Commutated Rectifier Universal Motor Controller with built-in sensorless microprocessor control circuit. It is used to control the speed and torque of Universal motors, from low-speed continuous operation up to ultra-high-speed operation. F5D4-NM10Y has wide application fields, including but not limited to air conditioners, washing machines, robot arm machines, food processing machines, elevator and funicular machines.

The electronic controller is the core technology of F5D4-NM10Y. All the system’s calculation and control process is conducted by an integrated microprocessor central processing unit (CPU). Programming parameters can be set by a dedicated software. Such as types of motor, maximum speed, over-rev (middle transition) speed, deceleration time, acceleration time, protection torque and so on.

In terms of working principle, the control operation of F5D4-NM10Y may be divided into two steps: supply phase commutation and motor phase commutation. In the first phase, the power supply drives the F5D4-NM10Y bidirectional rectifier and current output is enabled, while in the second phase, the rectified current drives the motor. The motor then responds according to its commutation angle and flux vector which can be set by programming parameters.

The F5D4-NM10Y employs a unique sensorless commutation method which enables the motor to produce a stable torque at any speed. Additionally, the built-in short-circuit protection guarantees the motor from damage due to overcurrent. To sum up, F5D4-NM10Y is an excellent motor controller with a wide range of applications due to its excellent performance, high efficiency and long-term stability.
