PMDC Gearmotor Does the Heavy Lifting
Battery-Powered Hollow Shaft Gearmotor Lifts More Than 400 lbs.
From manufacturing and retail to warehousing and distribution, no matter where you work, eventually you will need to move something heavy. While lifting equipment is used across almost every industry to make the job easier and safer, 32% of workplace accidents in 2016 were related to material handling according to The Traveler’s Insurance Companies. With that information in mind, when a global manufacturer of lifting equipment contacted us for a design solution, our team was ready to help.
The design required a small, high-torque gearmotor that would be capable of lifting and holding up to 200kg (440 lbs). Because the lifts were portable, the gearmotor would need to operate from 24VDC battery power. The customer wanted to avoid using external brakes, so the gear train would need to be strong enough to be self-locking even under heavy loads. Finally, they wanted the gearmotor to provide nearly silent operation.
The Bodine engineering team provided a solution based on our standard/stock hollow shaft 33A-GB/H gearmotor. Design features include:
- Unvented, maintenance-free gearhousing
- Hardened output gearing for high torque and compact size
- Special windings that provided higher speed and torque at 24VDC
- Metric shaft and mounting threads
- Improved enclosure and sealing with PG strain relief
- Stainless steel drive shaft
