    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

33BL 3 phase 24V 4000RPM 2A micro electric brushless dc motor

 

The 32mm gearbox has 3 stages of reduction ratio. The first stage has reduction ratios of 1:4 and 1:5, the rated tolerance torque is 0.3 NM, max at 1NM. The second stage has reduction ratios of 1:16, 1:23, 1:33. The rated tolerance torque for stage 2 is 1.2NM, max momentary tolerance torque is 3.5NM. The third stage has reduction ratios of 1:67, 1:94, 1:133 & 1:188. The rated tolerance torque is 2.5 NM, and max momentary tolerance at 7.5NM.

 

For the 33BL series, it is lightweight and space-saving, very suitable for those who are tight in install space.

Planetary Gearbox Applications

As well as uses for transmissions in vehicles, planetary gearboxes are used in various industries for different applications. They offer high precision and high torque-to-volume ratio making them well suited to applications that involve; increasing torque, reducing speed, precise positioning, and controlling reproducible machinery. Applications include:

 

  • AGV's.
  • Wheel drives.
  • Slew drives.
  • Winch drives.
  • Slew drives.
  • Track drives.
  • Mixing.
  • Pumps.
