    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

57BLF high torque NEMA 34 planetary gearbox motor with multiple material options

 

All the 57BLF brushless motors can match with powder metallurgy gearbox 42mm, 56mm, or Zinc alloy gearbox 52mm.

The max reduction ratio is 1:216 of 42mm gearbox, the rated tolerance torque is 10 Nm, and max momentary tolerance torque is 30 Nm. For the same amount of load capacity, our powder metallurgy planetary gearbox has a higher service lifespan than the traditional gearboxes. The key aspects are to improve efficiency and reliability in any mechanical system.

Advantage of gearbox motor

1.Increased repeatability: Its greater speed radial and axial load offer reliability and robustness, minimizing the misalignment of the gear.

2.Perfect precision: Most rotating angular stability improves the accuracy and reliability of the movement.

3.Lower noise level because there is more surface contact. Rolling is much softer and jumps are virtually nonexistent.

4.Greater durability: Due to its torsional rigidity and better rolling. Thus, greater efficiency of the gear and a much smoother operation is achieved.

5.Very good levels of efficiency: Planetary reducers offer greater efficiency

6.Increased torque transmission: With more teeth in contact, the mechanism is able to transmit and withstand more torque. In addition, it does it in a more uniform manner.

7.Maximum versatility: Its mechanism is contained in a cylindrical gearbox, which can be installed in almost any space.
