Permanent Magnet Fan Control Box

Adaptive Control Solution for Permanent Magnet Fan Systems

This Permanent Magnet Fan Control Box is developed by Wuxi Ruisida Electric. It is designed for industrial ceiling fan systems using permanent magnet synchronous motors (PMSM).

Different fan manufacturers use different motor parameters, which makes controller configuration and replacement more complex in practical applications.

This control box integrates an automatic parameter identification and tuning function. The system can recognize and adapt to common PMSM motor parameters, reducing the need for manual tuning when replacing or configuring motors.

Stable Operation with Optimized Control Algorithm

The control system is based on a large-inertia PMSM control algorithm designed for high-load ceiling fan applications.

It ensures smooth acceleration and deceleration without mechanical shock or oscillation.

A dedicated noise suppression strategy is implemented to reduce operating noise during continuous operation.

The system integrates comprehensive motor protection functions, including adjustable overload protection thresholds, helping reduce motor thermal stress and improve long-term reliability.

The control box is housed in a metal enclosure with integrated circuit protection, including a built-in circuit breaker for electrical safety and system protection.

The unit supports both 220V and 380V power supply configurations.

Power ratings include 0.75 kW and 1.5 kW, compatible with 0.75 kW to 1.5 kW permanent magnet synchronous motors.

All units undergo functional testing and aging inspection before shipment. Manufacturing is based on standardized production processes in our in-house facility.

Industrial Control Solution for Large-Scale Ventilation Systems

This control box is suitable for factories, warehouses, supermarkets, gymnasiums, and other large-space ventilation environments using PMSM ceiling fans.

We provide a 3-year warranty for the complete unit and long-term technical support. For international customers, remote debugging, video guidance, and online commissioning support are available.

Samples can be provided for evaluation before bulk orders.

This Permanent Magnet Fan Control Box provides adaptive motor matching, stable operation, and reduced maintenance requirements, improving overall system reliability in industrial ventilation applications.
