21 years of production of brushless power motors for electric tools with a small amount of originals,

High-power high-speed spindle motor.

Front and rear double ball bearings, rear cooling fan,

RuFeB high-strength magnetic rotor, the power is very strong.

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,

Applicable voltage 12-21V,

The specific voltage used is determined by the buyer according to the speed, etc.

The higher the voltage, the higher the speed, the greater the power, and vice versa.

The brushless motor of the power tool has no built-in drive,

You need your own driver to work.

The three wires coming out of the motor are three-phase wires.

Not positive and negative, do not directly connect to 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.

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 1.55A no-load speed 12500 rpm

DC 18V: no-load current 2.25A no-load speed 18800 rpm

DC 21V: no-load current 2.75A no-load speed 22000 rpm

A single motor weighs about 237 grams
