The product is the newest PMSM (Permanent Magnet Synchronous Motor Controller) This controller is designed with FOC (Field Oriented Control) algorithm, which uses SVPWM to control a power device to inject a sinusoidal current into a three-phase motor. Uses a 32-bit microprocessor that integrates an ARM core, it demonstrates excellent performance and task handling capabilities. The controller can handle torque, amperage, speed. Through these methods, the system can achieve the following performance results: maximum torque control, constant power control, closed-loop speed control and regenerative braking control feedback. Sine-wave controller for brushless motors. Built-in multi-level overload and overheating protection system, waterproof.
