Outer Rotor Brushless DC Motor 75mm

Product Description

The 75mm BLDC motor is an outrunner motor that consists of a high-quality stator, rotor, and position sensor. As a permanent magnet synchronous motor, it contains hall-effect sensors, which is high efficiency and can use in high temperatures.

As a customized motor, except for 24v, the rated voltage that we can supply includes 12v, 36v, 48v.

We ensure that it is an excellent choice because the price is affordable and quality is very high. We can provide full review reports if you need them.

Ability

What is the outrunner BLDC motor?

The internal rotor motor is the motor that the rotor rotates with a motor spindle. The motor frame is fixed, the shell is as the stator, and the internal and spindle as the rotor. The external rotor motor is that the rotor rotates with housing, the motor spindle is fixed, the internal and spindle are as the stator.
