The original power tool brushless power motor, high-power high-speed spindle motor, electric circular saw high-speed three-phase brushless. The frame of the motor body has a cast aluminum structure. The whole body is basically made of metal except for the built-in cooling fan. The material is very solid. The diameter of the internal coil reaches 0.9mm, which is very thick. The rotor is corrected by high-speed dynamic balance by cutting. Pian Ru iron boron high-strength magnetism, you can obviously feel the magnetic resistance is very large when you twist it by hand. There is also a rubber ring embedded in the inside of the bearing. The details are very good. In terms of coils and internal materials alone, the power of this motor should not be low, and the torque should be very good. The owner's actual test, 18V no-load current is nearly 5A, and the starting current is many times larger, which is very violent. Suitable for power tool repair and replacement or model DIY and other purposes.

The nominal rated voltage of the motor is 18V, the original matching 5S lithium battery wireless power tool, the applicable voltage is 12-21V, the specific voltage used is determined by the buyer according to the speed, etc. The higher the voltage, the higher the speed and the higher the power, and vice versa. The brushless motor of electric tools does not have a built-in driver. It needs to be equipped with a driver to work. The three wires coming out of the motor are three-phase wires, not positive and negative. Do not directly connect the power supply, it will directly burn the motor. Power supply requires high-power power supply or power battery power supply, otherwise the performance of the motor cannot be exerted, and the starting current is many times larger than the no-load current. The following simple test typical voltage parameters are for reference:

DC 12V: no-load current 2.82A no-load speed 12600 rpm

DC 18V: no-load current 4.62A no-load speed 18900 rpm

DC 21V: no-load current 5.12A no-load speed 22000 rpm

Compared with the electric tool motor sold by the owner before, the performance parameters of this motor are basically doubled, and it can be seen that this motor is very powerful.

A single motor weighs about 502 grams and is priced at a single motor.
