Product Description:
The SR3628-5387-7-1 is a brushed DC motor manufactured by Kollmorgen for the SR and SRF Permanent Magnet Motors series. It is intended for industrial automation applications that require steady torque from a low-voltage source, including compact conveyors, small presses, and positioning tables. Permanent magnets provide consistent magnetic flux without external field excitation, allowing the motor to operate with relatively simple speed-control equipment. This arrangement also avoids the electrical losses and additional wiring associated with a wound field. Its compact design supports installation in machinery where panel space and motor clearance are limited.
The armature is supplied with 90 VDC at its rated operating point. At this voltage, the motor draws 18.8 A and delivers a mechanical output of 2 HP while maintaining a shaft speed of 3200 rpm. The associated controller, cabling, and protective devices must be selected to accommodate this electrical load. The low base voltage keeps insulation stress modest, while the moderate current level permits use with commonly available DC drive equipment. The motor can be coupled to a gearhead or belt drive when the connected components remain within the permitted radial and axial bearing loads. Proper conductor sizing and overcurrent protection help prevent excessive voltage drop and overheating during sustained operation.
The motor uses an SCR-rated control interface, so its commutator can tolerate the chopped DC waveform produced by a silicon-controlled rectifier drive without excessive brush wear. It is designed for continuous duty, allowing uninterrupted operation at rated load when installation and operating conditions remain within permitted limits. A TENV housing protects internal components from dust by eliminating external ventilation paths, while heat passes through the enclosed frame to the surrounding air. Its permanent-magnet DC design eliminates field-winding losses and supports responsive speed changes when the controller adjusts armature voltage. Because cooling depends on heat transfer through the frame, the motor requires adequate clearance around its exterior surfaces and secure mounting to an appropriate machine structure.
