Product Description:
The SR5340-5370-45B is a permanent-magnet DC motor built by Kollmorgen and offered under the SR and SRF Permanent Magnet Motors series. In automated machinery, the unit converts electrical energy into rotational motion without requiring field-winding excitation. It can drive pumps, indexing tables, or gearboxes, while its permanent-magnet design simplifies wiring and eliminates the electrical power that a wound field would otherwise consume. The motor can be connected to a suitable speed controller when an application requires adjustable output rather than direct operation at its nominal point.
The motor is designed for a nominal terminal voltage of 220 V, which is the supply level used for rated operation. At that voltage, the armature draws 17.0 A, a value that must be considered when selecting conductors, fuses, contactors, and drive electronics. Mechanical output reaches 4 HP, providing continuous shaft power for the connected load when the motor operates within its thermal limits. Under these conditions, the rotor turns at 2590 rpm, allowing the shaft to be coupled directly to suitable equipment or connected through gearing for a different output speed. The TENV enclosure protects the windings from airborne contaminants and has no internal ventilation openings. Heat passes through the enclosure surface, so adequate space around the housing is necessary to prevent excessive operating temperatures.
The electrical circuit operates on DC supplied by a phase-controlled rectifier, and the stator magnets support smooth torque production at low speeds. Because the armature is SCR-rated, it can tolerate the commutation ripple and current pulses produced by silicon-controlled rectifier drives without excessive brush wear. A factory-mounted flywheel adds rotational inertia to the shaft and dampens speed fluctuations caused by cyclical loads. The added inertia also reduces abrupt velocity changes when load torque varies during a production cycle. A compatible torque-controlled converter can regulate armature current to manage acceleration and running speed. Proper controller selection must account for the motor’s terminal voltage, armature current, continuous output, and operating speed without duplicating field-control circuitry that the permanent magnets make unnecessary.
