Product Description:

The EP3620-1954-7-56BC-CU is a permanent-magnet DC motor manufactured by Pacific Scientific in its Permanent Magnet DC Motors series. It is intended for industrial automation tasks that require reliable direct-current drive performance and controlled rotary output. In service, the motor can provide steady shaft rotation for conveyors, small presses, and positioning stages connected to PLC-based systems. Its design also supports straightforward integration with electronic drive modules through simple two-wire power connections. Because it uses a permanent-magnet design, the motor does not require separate field excitation wiring. That arrangement helps keep the electrical connection simple in compact DC drive systems.

With a continuous armature current of 28.0 A, the motor delivers 12.0 lb-in of continuous torque under steady-state conditions. A 0.52 lb-in/A torque constant links torque output directly to current, which helps keep current-mode control predictable. A nominal supply of 12 V drives the armature to 1750 RPM, giving the motor a useful operating speed for compact fractional-horsepower machinery. The current-to-torque relationship is useful in systems that regulate motion by adjusting armature current rather than relying only on open-loop voltage control. This makes the motor response easier to predict during starts, stops, and load changes.

The motor uses a TENV enclosure and a 56C frame, so the housing is totally enclosed while remaining compatible with common C-face mounting hardware. A 5.875-inch mount bolt circle works with standard gearbox patterns, and the 4.500-inch pilot helps locate the motor concentrically during installation. The shaft measures 0.6250 inch with a tight -0.0005 inch tolerance for keyed couplings, and the overall length is 10.38 inches for compact machine layouts. The enclosed housing also helps keep shop dust and incidental debris away from the internal electrical parts. Electrical response is influenced by a winding resistance of 0.04 Ω and an inductance of 0.18 mH, which affect current rise and drive tuning. The motor is rated at 1/3 HP and weighs 19 lb, which is useful when bracket loading and mounting support are considered.
