Product Description:
The EP3624-2757-7-56BC-CU is a permanent-magnet DC motor manufactured by Pacific Scientific within the Permanent Magnet DC Motors series. This fractional-horsepower unit converts low-voltage DC input into steady rotary motion for conveyors, indexing mechanisms, and other position-controlled stages in industrial automation. When paired with a PWM drive, the motor supplies repeatable speed and direction control to downstream mechanical elements.
The motor is designed for a supply of 24 V DC, a level that simplifies integration into battery-backed or safety-extra-low-voltage panels. At the rated speed of 1750 RPM, it delivers the specified 1/3 HP of mechanical output. Continuous armature current of 13.4 A keeps winding temperature within thermal limits, and the resulting shaft torque is 12.0 lb-in, which is suitable for moderate inertia loads such as lead-screw drives. With a torque constant of 1.02 lb-in/A, the controller can infer produced torque from measured current for tighter closed-loop control. Armature resistance is 0.16 Ω and inductance is 0.66 mH, producing an electrical time constant near 4 ms so current settles quickly when the drive modulates PWM. A 4.500 in pilot diameter centers the housing, and the 0.6250 in shaft accepts standard keyed couplings.
Its TENV housing blocks dust and moisture while relying on surface conduction for heat removal, so ambient temperature must stay within the continuous rating. The NEMA 56C face mount shares bolt patterns with common gearboxes and pumps, which eases mechanical interchange. Overall length is 10.38 in, allowing installation in compact frames without excessive shaft overhang. A mass of 24 lb provides rotor inertia that smooths speed ripple yet increases acceleration demand on light loads. With no external fan, the motor operates quietly and avoids pulling contaminants through the windings.
