Technical description
High-Torque BLDC geared motor
The new drive technology of this high-torque BLDC motor makes it true: Very high efficiency by small dimensions and weight, an extremely steady, smooth and quiet running as well as a long lifetime.
This brushless motor operates on a patented axial flow double disc rotor principle with continuous commutation. The fully integrated electronics, which is matched to the motor characteristics, takes over the motion control. The geared motor achieves the exceptionally high torque density of 10 Nm with high overload capacity and adjustment dynamics. A specially developed air anchor principle is used instead of the usual slot anchor. This ensures perfect cogging torque, excellent running smoothness and fast and accurate fine positioning. Typical application areas where this high accuracy and reliability are important:
- Industrial Automation and Robotics
- Medical technology
- Measuring and imaging system technology
In addition to the electronic commutator, which is controlled by a programmable logic (CPLD), a microcontroller is integrated in the motor, which in the normal version controls direction, PWM speed with ramp functions for acceleration and deceleration as well as various protection functions and fault analyzes. An incremental encoder with pulse counter is also included, which can be used to control speed as well as the position in multi-turn mode. By modifying the firmware, it would be possible despite the large gear reduction to control an oscillating motion, as used in the windshield wiper drive, even over many motor rotations (transmission input). Thus, a single additional position sensor on the output - meaningful with switching point in the middle of movement - would suffice to detect the absolute position during switch-on (or during basic initialization) and then to perform a sine-like motion control in the reversal points. In addition to this smart motion, the wear of all moving parts and current peaks are reduced. In this case, the additional position generator can be directly connected with an input line of the integrated motor electronics, so that besides to a start-stop line no further external controls are needed. We will gladly check further special function on request.

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

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.
