Feature: 1. Have speed control function, include voltage speed control or single-chip microcomputer speed control, microcomputer control PWM speed control. 2. Made of high‑quality material PCB, sturdy and durable, have a long service time. 3. Possess favorable mechanical characteristics and adjustment characteristics, good linearity, wide speed adjustment range, long life, easy maintenance, low noise 4. Brushless Motor Controller's operating efficiency, low‑speed torsion, and speed accuracy of the brushless DC motor are better than those of any control technology inverter. 5. Small in size and light in weight, convenient to carry and use at any time, very convenient and practical. Specification: Item Type: Brushless Motor Controller Material: PCB Purpose: Brushless motor drive control Working Current: ≤15A Drive Power: ≤500W Working Temperature: -40-85℃ Humidity: 90% Rh Stall Protection: Yes Enable Control: Yes Overcurrent Protection: Yes Steering Control: Yes Speed Control Signal: Yes Power Terminal Output: VCC (positive power supply) GND (minus one) MC (Motor Phase W) MB (Motor Phase V) MA (motor phase U). Package List: 1 x Brushless Motor Controller Note: 1. If the heat sink you use is less than 60W and there is no additional heat sink, you must add a heat sink above 60W. If the driving efficiency of the heat sink is not reduced, excessive temperature will cause permanent damage.2. The size of the radiator may be based on harsh environment work (recommended cooling area is greater than 200 square centimeters).3. When installing the heat sink, be sure to pay attention to the insulation of the MOS tube on the back of the module. If there is no insulation, it will stick to the drive board and be permanently damaged.4. It is recommended to add thermal insulation film and thermal grease on both sides.
