ISL Products‘ Planetary Gear Motors are an inline solution providing high torque at low speeds. Our Planetary Gear Motors offer high efficiency and provide excellent torque output when compared to other types of gear motors. They can handle a varying load with minimal backlash and are best for intermittent duty operation. With endless reduction ratio options, voltages, and sizes, ISL Products has a fully tailored gear motor solution for you.

There are a few design features to consider when determining if an ISL Products‘ planetary gear motor is right for your application. The standard voltage is either 12VDC or 24VDC. As one of the worlds leading gear motor manufacturers, we can accommodate most customers who require 36VDC or 48VDC though. Our gear motors range in size from 8mm to 60mm in diameter. There are torque limitations to also consider, generally for this type of gear motor the maximum operating toque will be around 150 – (15-20Nm), depending on the overall size. Over the years we have developed some slightly larger solutions with more torque but most of our planetary gear motors fall within these confines.

More about Planetary Gear Motors…

A dc planetary gear motor from ISL Products features one of our various types of DC motors coupled with one of our uniquely designed planetary or epicyclic gear heads. When you couple a dc motor with a planetary gearbox a speed reduction occurs resulting in increased rotational torque at the gearbox output shaft. A planetary gearboxes consist of an internal sun gear that drives multiple outer ring 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.

A 12V Motor or 24V Motor 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 planetary gear motor 12vdc that we designed and manufactured for articulating tv mounts.

A stepper motor can also benefit from the addition of a planetary gearbox, allowing for enhanced torque while still maintaining the precision associated with stepper motors.
