New in the product catalog | BLDC motor with new planetary gear
In the new P042066 series, a BLDC motor is equipped with a new planetary gear in two variants. Both variants have double ball bearings and reinforced planetary gears.
Technical data of the LN planetary gear
- Voltage: 24 VDC
- Rotation speed: 11 to 800 rpm
- Torque: 0.5 to 13.2 Nm
- Gear with two ball-bearings and reinforced planetary gears
- A variant with helical-toothed plastic gears in the first stage
Advantages of this LN planetary gear
- High torques
- high efficiency
- Low gear backlash
- Low noise in the variant with plastic gears
Areas of application
- In high-precision applications that require low gear back lash, e.g. in the positioning of laser optics, in mechanical processing devices or in order picking systems.
- The variant with plastic planetary gears is mainly used in noise-sensitive applications.
Why does a manufacturer need this LN planetary gear?
- LN planetary gears are technically far superior to conventional planetary gears in all areas. Especially when it is controlled electronically, as the data can be utilized much more precisely.
- An LN planetary gearbox largely eliminates the weaknesses of a conventional planetary gearbox.
Differences between the LN planetary gear and conventional planetary gears
Double ball bearing
- Withstands radial forces better, e.g. mounted belt pulley.
- Protects the planetary gears from overload
- Significantly longer service life
- Higher power transmission possible
Reinforced planetary gears
- Improved force distribution due to wider contact surfaces
Plastic gears in the first stage
- Helical-toothed planetary gears
- Engage in stages
- Smooth transition of forces
- Reduced vibrations and shock loads
- Less noise
- Less wear
Comparison
- On the left, a conventional planetary gear with one ball-bearing and narrower planetary gears
- Right the LN planetary gear with double ball-bearings and reinforced planetary gears (here variant with helical-toothed plastic gears)

Series can be modified and extended to meet requirements
Here you will find your desired planetary gear motor in various series to help you make the right choice. The grouping into series indicates the respective case and identical gearbox parts. The other equipment can be optionally configured to suit the specific application.
- Modification of the output shaft with keyway or woodruff key, flats or additional internal threat
- Attachment of Hall-IC, encoder, tacho or brakes
- Assembly with attachments specified by you, e.g. rubber-metal buffer, clutch or angle bracket
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.
CAD data and motor characteristics
If you also require CAD data, we can provide it on request. We have CAD data and motor characteristics for each of our planetary gear motors. The latter show you the rotation speeds at which the corresponding torques are achieved. The current consumption is also shown.
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.
Interesting facts from the press
How does the planetary gear of an automatic gearshift in a vehicle work?
Planetary gears, also known as planetary gears, are machine components that are blessed with some very advantageous attributes and therefore shine in all kinds of applications. They function as distributor or summation gears, as very compact transmission stages and as the core of classic automatic transmissions.
