Electric Motor

For two decades, ascompressors.com has been the trusted authority in the refrigeration industry, specializing in compressors and their vital components. We understand that the electric motor is the driving force behind every refrigeration compressor and many crucial HVAC system components. A reliable, efficient motor is essential for consistent cooling performance, energy savings, and the overall longevity of your equipment. As your dedicated supplier, we offer a comprehensive range of high-quality electric motors designed to meet the rigorous demands of commercial and industrial refrigeration.

The electric motor converts electrical energy into mechanical energy, directly driving the compressor's mechanism to circulate refrigerant. Its efficiency, durability, and compatibility with the compressor design are paramount to the entire system's effectiveness.

Core Electric Motor Types and Key Products:

Our extensive inventory includes a variety of electric motors, carefully selected for their performance and reliability in refrigeration and HVAC applications. We focus on providing motors that offer seamless integration and robust operation:

  • Hermetic Motors: These motors are sealed directly within the compressor's casing, in direct contact with the refrigerant. They are primarily found in hermetic and scroll compressors. We supply replacement stator and rotor assemblies for these integral motors, ensuring a perfect fit and electrical compatibility with the original compressor design.

  • Semi-Hermetic Motors: Used in semi-hermetic reciprocating and screw compressors, these motors are housed within a bolted casing that can be opened for servicing. We offer complete motor assemblies, stator and rotor kits, windings, terminal boards, and related electrical components designed for the specific electrical and mechanical requirements of these compressors.

  • Open Drive Motors: These are external motors connected to the compressor via a shaft and coupling. Commonly found in larger industrial applications and some screw compressors. We provide a range of open-drive motors, including NEMA and IEC frame motors (e.g., TEFC - Totally Enclosed Fan Cooled, ODP - Open Drip Proof), offering various horsepower ratings, speeds (RPM), and voltage configurations (single-phase, three-phase) to match diverse operational needs.

  • Specialized HVAC Motors: Beyond compressors, we also supply motors for other critical HVAC components, such as condenser fan motors, evaporator fan motors, and blower motors. These are crucial for efficient heat transfer and air circulation within cooling systems.

We ensure our motor offerings include solutions for various power requirements, including energy-efficient options like Permanent Magnet (PM) motors and EC (Electronically Commutated) motors where applicable, helping clients reduce operational costs and meet modern energy standards. Our selection also covers critical motor accessories such as start/run capacitors, motor protection devices (overloads, thermistors), and wiring kits.

Essential Applications and Industries Powered by Our Motors:

The robust electric motors we supply are vital across a broad spectrum of commercial and industrial cooling applications:

  • Commercial Refrigeration: Driving compressors in supermarket display cases, walk-in coolers and freezers, beverage coolers, and ice machines.

  • Industrial Refrigeration: Powering large compressors in food processing plants, cold storage warehouses, breweries, and chemical facilities.

  • HVAC Systems: Operating compressors and fans in central air conditioning units, chillers, rooftops units, and air handling units for commercial and industrial buildings.

  • Specialized Cooling: Motors for medical freezers, environmental chambers, data center cooling, and industrial process chillers.

  • Heat Pump Systems: Providing reliable power for the compressor in both heating and cooling cycles.

Innovation, Efficiency, and Unrivaled Expertise:

At ascompressors.com, our 20 years in the refrigeration field have taught us that the motor's quality directly impacts system reliability and energy consumption. We are committed to supplying electric motors that not only meet but exceed industry standards for efficiency and durability. By choosing our motors, you're investing in reduced downtime, lower operating costs, and enhanced performance for your entire refrigeration or HVAC system. Our technical team possesses the deep knowledge required to assist you in selecting the ideal motor for your specific compressor or application, ensuring perfect compatibility and optimal operation. Trust us to power your cooling solutions with precision and expertise.

Electric Motor Buyer's Guide

Pre-Order Inquiry
Pre-Order Inquiry: The "Identity First" Guide

The Nameplate is Key: The model number alone is sometimes insufficient. We request a clear photo of the manufacturer’s metal nameplate. This confirms the specific Series, Voltage, and Bill of Material (BOM) number.

Refrigerant Verification: You must confirm the gas type (e.g., R134a, R404A, R290, or R410A). Using the wrong refrigerant in a Electric Motor compressor designed for a different gas will lead to immediate failure and void the warranty.

Voltage & Frequency Check: Global power grids vary. Whether you need 115V/60Hz (USA), 220V/50Hz (Europe/Asia), or 3-Phase 380V, this must be explicitly confirmed during the inquiry stage to prevent electrical burnout.

Eliminate compatibility errors before the order is placed. To ensure you receive the exact compressor needed for your HVAC or refrigeration system, we adhere to a strict "Identity First" protocol.
Parameter Matching Testing Reports
Technical Validation: Parameter Matching & Testing Reports

Application Matching: We verify if your application requires LBP (Low Back Pressure for freezers), MBP (Medium), or HBP (High Back Pressure for A/C and chillers). Installing an LBP compressor in an HBP application will cause the motor to overheat.

Performance Benchmarking: Before shipment, units undergo rigorous testing for volumetric efficiency, motor amperage draw, and noise levels

The Test Report: For peace of mind, we can provide a Quality Inspection Report or a video of the Electric Motor compressor under load test, proving it holds pressure and operates within factory specifications before it leaves our facility.

Prove performance and reliability through data. Once the model is identified, we focus on technical validation and quality control.
Supply Strategy: Inventory Matching, Batch Production
Supply Strategy: Inventory Matching & Batch Production

Spot Buy (Ready Stock): For urgent repairs, we leverage our global inventory of popular brands (Tecumseh, Copeland, Danfoss) to offer "2nd-Day Dispatch" on common Electric Motor models.

Batch Production (OEM Orders): For distributors or appliance manufacturers requiring 50+ units, we schedule a production run. This typically requires a 2-4 week lead time but offers significant cost savings.

Condition Clarity: We clearly distinguish between "Factory New" (fresh production) and "New Surplus" (older stock). We allow you to choose based on your budget and warranty requirements.

Optimize lead times based on your urgency and volume. We offer flexible solutions depending on whether you are replacing a single unit or stocking up for manufacturing.
Global Shipping
Logistics & Distribution: Global Shipping

Robust Crating: We do not use standard cardboard for international freight. All compressors are bolted to a pallet and sealed in fumigated wooden crates compliant with ISPM 15 standards for global entry.

Upright Transport: Compressors must remain upright to prevent oil from entering the compression chamber (which causes "liquid slugging"). Our packaging includes "This Side Up" shock sensors and indicators.

Customs & Documentation: We handle the complex paperwork, including Commercial Invoices and Certificates of Origin, ensuring your goods clear customs smoothly whether shipping via DHL Air Express or Sea Freight to any port in the world.

Ensure the heavy, precision equipment arrives undamaged. Electric Motor compressors are heavy, oil-filled components that require specialized handling for international transport.
