More about Planetary Gear Motors…

A dc planetary gear motor from ISL Products features a micro motor coupled with one of our uniquely designed planetary or epicyclic gear heads. We can utilize a variety of brush dc motor or brushless dc motors when configuring our gear motors. When you couple a dc motor with a planetary gearbox a rotational speed reduction occurs resulting in increased rotational torque at the gearbox output shaft. A planetary gearboxes consist of an internal sun gear (central gear) that drives multiple outer ring gears (outer gears) known as planet gears, hence its name. Multiple contact points across the planetary gearbox design allows for higher torque generation compared to a spur gear motor. For added strength and reliability, most are constructed with a metal gearbox. In certain situations, we can also provide plastic gearing. An ISL planetary dc gear motor has the ability to handle various load and or speed requirements while also serving as an excellent option for continuous torque loads. Once we determine the gear motor output requirements we can configure the correct reduction gear ratio. With decades of experience, we have endless gear ratio options to couple with our electric motors.

Motor Selection Guide

A mini dc motor with a nominal operating voltage of 12V or 24V can produce significantly more torque with the addition of a planetary gearbox. If your application requires additional torque, be sure to check out or wide selection of direct current gear motor options. As a renowned dc motor manufacturer, we are able to offer either brushed or brushless motors with our planetary gear motors. For devices and applications that require additional control, we can provide a gear motor w/encoder. Check out the 12V DC gear motor that we designed and manufactured for articulating tv mounts.

Efficiently Designed Right Angle Gearmotors

We offer the option to add an additional right angle bevel gear head to our planetary gearmotors for applications with mounting constraints. Our bevel gear reducers are very efficient and come with a 1:1 reduction allowing them to maintain optimal gearbox performance. They’re constructed of metal gears as well to maintain a robust design.

Planetary Gearbox vs. Spur Gearbox

High Performance Brushless Gear Motors

ISL Products also offers a variety of Brushless DC (BLDC) and brushless miniature gear motors. When we couple our bldc motor with one of our planetary speed reducers, these motors will provide an even higher torque output, compared to a similarly sized brushed motor. The brushless dc motor design also eliminates the need for regular maintenance that is associated with brushed dc motors. Thus brushless dc motors have a much longer use life and generate less ambient noise.

Our brushless geared motor solutions are the ideal motors for applications requiring precise control, such as robotics and automation equipment. Their high-efficiency design helps keep operating losses to a minimum while still providing the necessary power and torque for your application. Our brushless planetary gearmotors are available in a range of operating voltages: 6VDC, 12VDC, 24VDC, 36VDC and 48VDC. This variety allows you to customize the motor to your exact needs.

We also offer our gearbox solutions for other types of bldc motors, such as our hybrid stepper motors. This allows for enhanced torque while still maintaining the precision and accurate control associated with steppers.

For common customizations, we can make modifications to our standard BLDC planetary gearmotor models to meet additional requirements you may have. Our engineers will provide product documents and specifications prior to manufacturing for your approval. As an industry leader with an ISL Products’ brushless geared motors, you can be sure that your application will operate reliably and efficiently!
