398_PittmanMotors_EC042B-PR-Pittman Motors EC042B brushless DC motors are equipped with a NEMA-17 mounting configuration that adapts to most metric mounting requirements so they’re easy to upgrade for many stepper motor applications.

The motors, available in three motor lengths with a continuous torque range of 11 to 31 Ncm (peak range of 35 to 99 Ncm), have a maximum rpm of 9,000 and are used with DC bus voltages up to 96 V. There are eight standard winding variations and custom windings to meet exacting end-product requirements.

A high-energy, 4-pole rotor with rare earth magnets improves the motor’s high torque to inertia ratio. The stator assembly is produced with low-loss materials for higher-speed applications. Shielded ball bearings support the motor shaft, which is preloaded to reduce vibration.

Pittman PLG42S and PLG52S planetary gearboxes and optical incremental encoders are optional with line counts up to 2048, three channels and line driver.

Pittman is a manufacturer of DC motors based in Harleysville, Pa.
