Product Description 36V 40V 700W Brushless Motor Speed Controller Electric Garden Machinery Motor Speed Governor Three-phase Brushless Drive No Hall No Hall brushless controller, nominal 36V lithium battery power supply, the maximum power of about 700W, electric garden machinery tools, it is estimated that the hand push lawn mower drive, this automatic and stable speed drive, about the speed limit of no-load about 80 percent , the speed limit is not very big, the normal load speed of the motor basically will not change much, the motor under the large load speed will decline, The use characteristics and ordinary brushless driver are basically the same, the general motor with load speed will decrease a lot, the greater the load the greater the current is the lower the relative speed, in addition to the basic servo motor all DC motors are such characteristics. Not all motors can be compatible with brushless drive. Whether they are suitable needs to be measured by ourselves. Generally, brushless motors with medium and low speed operation are compatible with better points. Drive measured 30-43V can run, no hall high power driver, internal work material is very good, high power 70V120A MOS tube, large current parts are pressed copper plate positioning and drag solder, many big brand controller is at most added copper wire and solder, motor output three-phase wire is 14AWG high temperature silicone wire. The controller connection is defined in the introduction figure. Be sure not to connect randomly, otherwise it is easy to damage the drive.
