40V 900W High Power Brushless Motor Controller Constant Speed Electric Garden Machinery Three-phase Brushless Driver No Hall Specifications: No Hall type brushless controller, rated 40V900W, used in electric garden machinery, similar to lawnmower or lawn mower, the drive is speed limited constant speed operation, regardless of load and no load will be controlled in the nominal speed range, the speed depends on the motor parameters, not all motor speed is the same, Approximately limited to the motor test voltage 36V no-load speed of about 70% of the operation, the motor load with the speed up basically will not change, the motor speed preservation margin is very large, the power supply voltage level will not affect the speed level change. Brushless drive not all motors can be compatible with use, the specific application needs to know their own measurement, the general compatible point of the brushless motor running at low speed. Drive measured 30-43V can run, no hall high-power driver, internal work material is very good, high-power 75V190A MOS tube, large current parts are stamped copper plate positioning and drag solder, motor output three-phase line is 12AWG high temperature silicone wire, power plug is 60A gold-plated jack. The controller connection is defined in the introduction diagram. The detection signal line needs to be connected to the 10K resistance and the negative electrode, and the starting line is connected to two control switches. After the power is switched on, the starting line can start and run. The controller weighs about 300 grams. Note: 1. Due to the light and screen difference, the item's color may be slightly different from the pictures. 2. Please allow 1mm-1cm differences due to manual measurement. Package Included: 1x Brushless Motor Controller
