Leeson 108022.00 DC Permanent Magnet Motor
This Leeson 108022.00 is a DC permanent magnet motor rated at 1 HP and 90 V DC. It uses a 56C frame with a face and base mounting arrangement and a removable base. The motor is built for continuous duty in HVAC control applications.
Capacity and headroom
The motor delivers 36 in-lb of full-load torque at 750 RPM while drawing 10.0 A. Its service factor is 1, so it has no overload margin beyond the nameplate rating. Operation is limited to a maximum ambient temperature of 40 degrees C.
Thermals, noise and power draw
The totally enclosed fan-cooled enclosure manages heat during continuous operation without external ventilation. Insulation class F supports the rated temperature rise. No thermal protection is fitted, so the installer must provide external safeguards. The unit runs on 90 V DC supply.

Questions about this item
Will the 56C face mount and 5/8 in shaft match the pump coupling I already use?
The motor uses a 56C frame with a removable base and a 5/8 in diameter shaft that is 1 7/8 in long, so it fits standard 56C couplings and mounting patterns.
How can I confirm the 90 V DC supply is delivering the rated 10.0 A at 1750 RPM?
Measure the DC voltage at the terminals under load and the current draw with a clamp meter; the nameplate shows 1 HP at 1750 RPM with 10.0 A full-load amps.
Does the box include a mounting base or do I need to order one separately?
A removable base is built onto the motor, so no separate base is required for face or foot mounting.
