Permanent Magnet DC Gearmotors Have High-Torque GearheadThe WX gearhead is now available with two 33A permanent magnet DC (PMDC) motors. The WX is a high-torque gearhead built to provide longer life and higher performance than similar gearmotors in the same size range. These gearmotors are designed to drive applications such as medical devices.

The WX gearmotors feature all-steel gear trains and synthetic lubricants, allowing the WX to produce up to 65% more torque than previous models. The steel gearing is designed to meet or exceed AGMA 9 standards to ensure quiet operation. The synthetic lubricant improves efficiency and allows these gearmotors to operate in a wide temperature range. Accessories include a bolt-on adaptor to convert the gearhead to three-point mounting pattern, as well as an “L”-braket for flexible mounting and a IP-44 protection kit. Forty-eight new stock models feature 12 available gear ratios, ranging from 4:1 to 312:1, and rated output speeds from 658 to 2.9 RPM.

A low-voltage type 33A PMDC motor with a winding rated 12/24 VDC and a standard 90/130 VDC motor are available to power the WX gearhead. Both motors provide high starting torque and linear speed torque characteristics. They feature permanently lubricated ball bearing construction for maintenance-free operation, as well heavy gauge steel housing and copper graphite brushes. The motors are totally enclosed, non-ventilated (TENV), and contain a Class F rated insulation system. Their windings are resin-impregnated to provide reliable performance in the most demanding applications. The motor armatures are designed to minimize cogging and to operate quietly. “Accessory ready” models allow for easy external mounting of encoders or brakes.
