HVAC ECM Blower Motor
This US Motors 5642 is a 3/4 HP ECM direct-drive blower motor built for HVAC air-handling equipment. It delivers nameplate speed of 1075 rpm and fits a 48Y frame with a single shaft and band mounting for horizontal installation.
Voltage and Frequency Limits
The motor operates on single-phase 115/208-230V AC at 60/50 Hz with full-load amps of 9.3 at 115V and 5.8 to 5.4 at 208-230V. It is rated usable at 208V but not at 200V, so installers must verify supply voltage before wiring.
Thermal and Duty Rating
Continuous duty is supported with automatic thermal protection and Class B insulation at a maximum ambient temperature of 40 degrees C. Buyers needing operation above that temperature or a different frame size should select another motor.

Questions about this item
Should I choose the 115 V or the 208-230 V wiring for this 5642 motor?
The motor is dual-voltage rated at 115/208-230 V AC. Wire it for the supply voltage you have available; full-load amps are 9.3 at 115 V and 5.8-5.4 at 208-230 V.
What does the 1075 rpm nameplate speed mean once the blower is installed?
1075 rpm is the rated shaft speed under full load at 60 Hz. Actual speed will follow the supply frequency and load; at 50 Hz the synchronous speed drops proportionally.
Is the 48Y frame compatible with standard residential furnace mounts?
The 48Y frame with band mounting and horizontal orientation fits many direct-drive blower housings. Verify the band diameter and shaft dimensions against your existing housing before installing.
