Product Description

Rare 725 Little Fatty high-speed power tool, electric drill, electric saw, power motor.
725 motors, especially high-speed power types, are very rare to encounter,
And this batch of motors is from Taiwan's major motor manufacturer NICHIBO,
The work materials are naturally very good,
Front and rear double ball bearings,
5High-speed dynamic balance correction of extremely torque rotor,
Comes with cooling fan,
The rear part can replace the compensation type carbon brush holder,
Long life of carbon brushes with high copper content.

The motor has a nominal DC14.4V,
It was originally supposed to be used in power tools or power models with 4S.
14.4V no-load test speed 21500 rpm,
The starting current reached more than 20A,
No-load running current 4A,
Very violent.
So please make sure that the power or battery pack in your hand is sufficient,
Otherwise, the motor performance cannot be exerted.
But it needs to be reminded that the power density of this motor is very high,
Such high power density motors are not suitable for long-term operation.
Be sure to prepare a heat dissipation environment.
It is better to add some oil to lubricate the stock motor for the first time.

The following test parameters are for reference. The higher the voltage, the greater the power and torque. Buyers can choose the voltage according to their own situation:

DC9V no-load current 3.5A speed 13500RPM

DC14.4V no-load current 4A speed 21500RPM

A single motor weighs 245 grams
