Regal Rexnord
HVAC / R Motors
Regal Rexnord HVAC / R motors are purpose - designed electric motors engineered for the specific electrical, thermal, and mechanical demands of commercial and residential heating, ventilation, air conditioning, and refrigeration equipment.Under the Marathon, LEESON, and Fasco brands, our HVAC / R motor line includes permanent split capacitor(PSC) motors for direct - drive fans, three - phase motors for large air - handling units and cooling - tower drives, ECM(electronically commutated motor) high - efficiency designs for variable - speed applications, and specialized compressor - duty and condenser - fan motors in NEMA and OEM - specific frame configurations.HVAC equipment manufacturers, building - service contractors, and facilities maintenance teams select Regal Rexnord HVAC / R motors for their reliability in the demanding operating conditions of rooftop units, chiller packages, air handlers, and reach -in freezers — where motors must start under load, operate in ambient temperatures from - 30°C to 65°C, and survive years of continuous or high - cycle duty with minimal maintenance.With UL - recognized components, agency certifications for energy - efficiency programs, and stocked inventory across North America, our HVAC / R motors keep conditioned air and refrigeration systems running reliably, efficiently, and compliantly.

Trusted by Industry Leaders
ECM High - Efficiency Variable - Speed Designs
Electronically commutated motor technology reduces fan energy consumption by 30 % to 60 % compared to PSC motors, meeting ASHRAE 90.1 and regional energy - code requirements.
Compressor - Duty Ratings for Refrigerant Service
Motors specifically rated for the high starting torque and continuous - duty requirements of reciprocating, scroll, and screw compressors, with Class B or F insulation and refrigerant - compatible materials.
Condenser - Fan Motor Environmental Protection
TEFC, ODP, and TEAO enclosures with shaft seals, moisture - resistant insulation, and corrosion - protected hardware designed for outdoor, rain - exposed, and roof - mounted installations.
OEM - Specific Frame & Mounting Configurations
Motors designed to match the exact bolt - circle, shaft dimensions, and wiring connections of Carrier, Trane, York, Copeland, and other major HVAC equipment OEMs — direct drop -in replacements.
UL, CSA & Agency Certifications
Recognized components meeting the safety and performance requirements of North American and international HVAC equipment standards, simplifying OEM end - product certification.
Nationwide Distributor Stocking
The most common HVAC / R motor ratings and frame sizes stocked at distributor locations across the continent, with same - day pickup or next - day delivery for service - contractor emergency repairs.
ECM Motor Retrofit: Reducing Fan Energy Costs in Commercial Buildings
Commercial buildings consume significant electrical energy moving air through supply, return, and exhaust ductwork.Retrofitting existing PSC direct - drive fan motors with high - efficiency ECM motors can reduce fan energy consumption by 30 % to 60 %, often paying back the retrofit cost in under two years.ECM motors also provide built -in speed control — either through a fixed speed tap selection or a 0 - 10V variable - speed input — enabling demand - controlled ventilation strategies that further reduce energy use and improve occupant comfort.Regal Rexnord offers ECM retrofit kits that include the motor, mounting adapter, wiring harness, and speed - control interface, designed for straightforward replacement of standard 48 - frame and 56 - frame PSC motors in air handlers, fan - coil units, and packaged terminal units.The energy savings, combined with utility rebates in many jurisdictions, make ECM retrofit one of the highest -return investments available to building owners and facility managers.
HVAC / R Motor Reliability & Preventive Maintenance
HVAC / R motor failures during peak cooling or heating season can cause tenant discomfort, product spoilage in refrigerated storage, and costly emergency service calls.A preventive maintenance program that includes bearing lubrication(where applicable), belt tension verification, amp - draw measurement, and winding insulation testing can identify motors approaching failure before they interrupt service.Regal Rexnord supports HVAC / R motor reliability with maintenance training materials, motor - condition assessment tools, and a nationwide network of service - centers that can bench - test and recondition suspect motors during off - season periods.For critical applications — hospital ventilation, data - center cooling, refrigerated warehousing — we recommend maintaining an appropriate spare motor inventory, with our application team assisting in identifying the critical motor types and the most cost - effective stocking strategy to minimize downtime risk.
