Product Description:

The STF3624-5604-61-56C is a direct current motor produced by Pacific Scientific within its Permanent Magnet DC Motors series. In automated conveyors, feeders, and small-scale actuators, the unit converts controlled electrical energy into rotational motion that can be regulated by a closed-loop or open-loop speed controller. By providing torque from a compact frame that integrates easily with common gearheads or pulley sets, the motor serves as a straightforward prime mover for applications that need stable speed control and a compact installation footprint.

This model is designed for a nominal supply of 90 VDC; at that voltage, it draws approximately 4.9 A under full load. The armature current is compatible with controllers that deliver a full-wave, single-quadrant output because the motor is SCR-rated. A totally enclosed, non-ventilated housing, identified by the TENV code, keeps internal components free from airborne contaminants, so ambient airflow is not needed for cooling. When energized through a suitable thyristor drive, the motor reaches a rated speed of 1750 RPM, providing a standard base speed that suits common belt drives, rollers, and direct-coupled loads.

The external construction supports washdown duty, allowing high-pressure cleaning cycles without compromising lubrication seals or bearing service life. A NEMA C face permits direct coupling to compatible reducers and pump heads, helping maintain accurate mechanical alignment at the mounting surface. Sealing meets the IP65 classification, so dust ingress is prevented and water projected from any direction will not reach live parts. The motor uses a permanent magnet DC field system, which eliminates excitation losses and supports a linear speed-to-voltage relationship for straightforward analog speed regulation during intermittent-duty positioning and transport tasks.
