Product Description:

The SRF5360-4985-84-5-82BC-CU is a permanent-magnet direct-current motor built by Pacific Scientific and supplied within its Permanent Magnet DC Motors series. In conveyor lines, indexing tables, and other low-voltage motion zones, the unit converts regulated DC power into controlled rotary torque for machine axes. By integrating field magnets with the armature, it maintains steady torque across a broad load range while reducing brush maintenance. This construction allows direct shaft coupling to gearboxes or pumps without external excitation hardware.

At the nominal operating point, the motor accepts a supply of 180 VDC and draws a continuous armature current of 9.5 A. Under these conditions, it develops 72.0 lb-in of torque while turning at 1750 rpm, delivering a mechanical output of 2.0 HP. The Totally Enclosed Fan Cooled enclosure directs airflow with an internal fan so dust and oil mist cannot reach the windings. A 145TC/182 NEMA frame pattern with a 4.500-inch pilot diameter aligns the end bell to standard reducers, and the 0.875-inch shaft is furnished with a 0.188 x 1.38-inch keyed slot for positive coupling. Overall length is 16.50 inches, allowing the 75-lb housing to fit inside compact drive cabinets on machine frames.

For short-duration accelerations, the amplifier may supply a peak armature current of 78.0 A, raising shaft torque in proportion to the winding constant of 8.2 lb-in/A. Dynamic response is shaped by the armature circuit's 0.6 Ω resistance and 7.0 mH inductance, and these values limit current rise time while filtering commutation ripple. Heat generated during these transients is removed by the integral fan inside the housing, keeping the internal temperature within magnet limits and eliminating the need for external blowers. Frequent start-stop cycles are supported without compromising commutation life.
