PFM-42P DC

Classification：Brushed DC Planetry Gear Motor

The rated torque in the table is the product of dc motor rated torque,gearbox ratio and efficiency, rather than gearbox rated torque. The highest torque of gearbox refers to max stage short time torque. At rated torque, the gearbox generates reliable output performance, however, the life time shall subject to the real working cycle condition in the site(for example, at the same rated torque, the slower the speed, the slower the wearing out and the longer the life time.

Customized motor specs, shaft and encoder service is available.
