    I purchased the 3-pack of the smaller steppers for my current ender 3 pro project. For my applications, they work perfectly. It's a great deal for quality motors, and I'm going to purchase another 10 packs.

    These are great motors and they are very strong. They are operating quietly, and also need them to release their hold every time a move is complete.

Product Description

42BLY NEMA17 Customized Specification IP40 high torque brushless dc motor


Hetai 3 phase brushless DC motors offer the advantage of

long lifespan

low maintenance

high performance


The series has a wide range of speed and diameter from 22mm to 110mm with a hall sensor.

The Hall element is a magnetic field sensor whose function is to detect the position of the magnetic pole. Since the result measured by the Hall is only a pulse, it plays a role in controlling the speed of the brushless motor.


Encoder, brake or gearbox can be applied in our bldc motor to satisfy the customers' needs.
