SR3642-4822-7-56BC-CU

SR3642-4822-7-56BC-CU is a Pacific Scientific motor in the Permanent Magnet DC Motors series. It operates at a rated voltage of 90 VDC and provides 1/2 HP of rated power at 1,750 RPM. The motor produces 18.0 lb-in of continuous torque while drawing 4.7 A continuously. Its peak current is 74.0 A for short-duration operating demands, and its torque constant is 4.2 lb-in/A, indicating the torque produced per ampere.

The motor has 0.9 Ω of resistance, which affects current flow and electrical losses, and 3.8 mH of inductance, which affects the rate of current change in the winding. Its TENV enclosure is totally enclosed and non-ventilated, protecting internal components without using external ventilation.

The 56C frame supports standardized mechanical mounting. Its mounting interface has a 5.875-inch bolt circle and a 4.5000-inch pilot diameter for alignment. The shaft diameter is 0.6250 inches, and the shaft key measures 0.188 inches wide by 1.38 inches long for transmitting torque to the connected load. The motor has an overall length of 12.10 inches.
