Precision Custom Brushless DC Gearmotors

Our Custom Brushless DC gearmotors marry together a compact but powerful brushless DC motor, high performance drivers, rugged gearcase, and other accessories you may require. Providing precision and longevity to your next project.

Increased Efficiency.
Precision Control.
Extended Lifespan.

For an electrically efficient solution with virtually no maintenance needed, consider one of our Brushless DC gearmotors (BLDC). Powered via electrical commutation, Brushless DC motors don’t require brush replacement and ask for very little maintenance, in general. They also boast an extremely long life of 20,000+ hours, from 5 to 10 times longer than a brushed DC. BLDC motors are compact, precise, and provide more power density for tight spaces. High energy efficiency is another notable feature. More work accomplished with less input wattage is a great benefit. BLDC gearmotors are designed for intermittent or continuous duty and have zero EMI emissions. They also offer precision controllability across a range of speeds. Choose from our three BLDC options, all featuring a single 42mm frame size, neodymium magnet technology, 6-pole stator and slotless rotor design, and heavy-duty ball bearings.

  • EZ Drive 

Utilizes a simple onboard motor drive system with easy 4-lead power, brake, and forward/reverse wiring for plug and play usability.

  • Hall Effect

Designed to connect to an external drive system utilizing the three onboard Hall Effect sensors for control and positioning. Hall Effect firing Sequence provided.

  • Digital Drive

The most controllable motor in our line. The integral motor drive system can use digital signals from external sources to control the speed, torque, and position of the motor.

As with all our custom motor options, we will tailor engineer speed, and torque-carrying capacity according to your specs. We can supply the motor by itself, or be fitted to comprehensive range of Multi’s standard parallel shaft, compact in-line, and planetary gearboxes/reducers. Our gear reducers support speeds from .25 RPM through 400 RPM, voltages from 6 to 90 VDC, and torque carrying capacity up to 250+ in-lb continuous. Customize your shaft design, as well, with case hardening, bushings, dual outputs, or needle or sealed ball bearings. Gearboxes are permanently lubricated with synthetic gear grease, with the option to use NSF-rated grease. And you can choose plastic or fiber gearing material when noise reduction is a concern.

In addition, you can further customize your BLDC motor and gearbox with a variety of value-add upstream actuation accessories and downstream sub-assembly solutions. Add encoders, custom wiring harnesses, mounting plates, couplings, steel-cut or powdered metal gears, pulleys, cam/switch actuators, bushings, needle, ball, or sintered bearings, tappings, holes, flats, hollow or thru-shaft design, custom sub-assembly, or other components directly to the gearmotor for a unique, custom-designed product.
