The LRPX series carefully integrates the unique RPX series brushless motor with a custom planetary gearbox. The result is a small form factor brushless DC gearmotor that can produce incredibly high torque at low speeds, providing powerful, efficient and smooth operation with low noise! Typical small-frame BLDC motors have peak performance at very high RPMs. These speeds are simply too high to make efficient use of a gearbox, and even when a typical BLDC motor is paired with a custom high-rpm gearbox, usually there are noise and heat issues that make it prohibitive for a variety of applications. The LRPX design is optimized to perform with peak efficiency at more traditional motor speeds, offering significant advantages to customers, not only in torque output, but also in reliability and overall cost.
ElectroCraft Series 116 and 121 gearmotors match our 1.6" and 2.1" diameter DC brush motors with either metal or plastic/polymer planetary gearing. This is an ideal gearmotor for medical applications where strong, coordinated, accurate motion control is required. The planet gears share the load attached to the output shaft giving the planetary arrangement a higher torque to volume ratio with low backlash compared to a spur gear arrangement. Gear ratios up to 642:1 are available. Encoders can also be added.
ElectroCraft offers a 2" diameter spur gearbox that is compatible with our 1.4", 1.6" and 2.1" diameter DC brush motors. These gearmotor packages are offered in a wide range of operating voltages and 4 gear ratio options, 12:1, 48:1, 192:1 and 768:1. Optional features include encoders, noise suppressors, custom shafts, custom leads and terminations, custom mounting and rear shaft extensions.
