The complex design of a planetary gear motor

The exploded view shows the complex design of a planetary gear motor with a three-stage gear. Each gear stage reduces the rotation speed and increases the torque. The high torque is distributed over several gear wheels. The gears in the first stage are usually made of plastic to reduce noise. The first stage rotates very quickly - most DC motors at 5000-9000 rpm. The other gears are made of plastic or steel. If a different gear ratio is required, we can easily equip the DC motor with a different gear to suit your application.

A planetary gear motor can be louder than a DC motor with a different type of gearbox. Any noise that occurs can be additionally insulated by installing helical gears. We know how different noise emissions are from cars, for example: forward gears are usually helical and quiet, while reverse gears are usually straight and make a characteristic whining noise.

Unfortunately, it is often neglected that simply using a long-life grease helps a planetary gear motor to be very reliable and durable.

Planetary gear motor | Your questions & answers

A motor characteristic curve is a diagram that shows the behavior of a planetary gear motor based on current consumption, rotation speed and torque.

Yes, almost all of our control systems are PLC-compatible.

A Hall-IC is a sensor that detects magnetic fields. It is often used in conjunction with a planetary gear motor to determine rotation speed and rotation direction.
