Overview
The QM Power Q-Sync QSM50-1A-A2-F, manufacturer part number 30044-00, is a constant-speed, 38–50 watt commercial refrigeration fan motor rated for 115VAC, 60Hz operation at 1800 RPM.
The exact label specifies CWOSE rotation, meaning clockwise when viewed from the end opposite the shaft. The motor is thermally protected, carries an exact-unit IP65 water-and-dust rating, and is labeled for an operating-temperature range of −40°C to +55°C.
The nameplate carries the UL Recognized Component mark for Canada and the United States under file E465664 and references U.S. Patent No. 9,300,237.
QM Power describes the Q-Sync 38–50W family as a permanent-magnet synchronous motor platform for compatible commercial-refrigeration evaporator and condenser fan and blower applications. Typical family applications include walk-in food coolers, freezers, and external refrigeration rack units. These are family-level application categories and do not establish fit for a particular equipment model.
Order this motor as an exact identity match when the existing motor carries model QSM50-1A-A2-F and/or part number 30044-00, and when all electrical, directional, mechanical, connector, and fan-loading requirements match.

Questions buyers ask
- Is QSM50115CW the same as QSM50-1A-A2-F?
- QSM50115CW is distributor and catalog shorthand. It is not proof that every QSM50 suffix is interchangeable. Verify the complete model suffix, RPM, rotation, shaft, connector, mounting, and blade requirements before substituting.
- What horsepower is this motor?
- No horsepower rating is printed on the nameplate. 38–50 watts falls near the 1/15 HP market class, which is useful for searching, but we do not publish an exact horsepower specification for this unit.
- What does CWOSE mean on a QM Power motor?
- CWOSE means clockwise when viewed from the end opposite the shaft. It does not mean clockwise when looking directly at the shaft. Confirm the viewing direction whenever comparing motor rotation.
- Is the model number the same as the part number?
- No. The model identifies the motor configuration, while the manufacturer part number is a separate catalog or inventory identifier. For example, QSM12-1A-A2-F is the exact model and 30021-01 is the manufacturer part number. Search and compare both.
- Can a 1550 RPM motor be replaced with an 1800 RPM motor?
- Not automatically. A different-speed motor can change airflow and fan load. Confirm blade diameter, pitch, weight, required airflow, rotation, shaft, mount, and motor load before changing RPM.
- Is the fan blade included?
- Not unless it is expressly shown and listed under What's Included. A motor listing should not be assumed to include a fan blade, basket, shroud, bracket, or mounting hardware.
- Will these motors fit any commercial refrigerator?
- No. Commercial refrigeration motors are selected by model number, manufacturer part number, voltage, frequency, wattage, RPM, rotation, shaft, mounting pattern, connector, blade, airflow, and load. Matching only the voltage or body shape is not sufficient.
- Are these new, used, or new-old-stock motors?
- The condition shown on each listing comes from our own inventory record. These parts have been physically verified and are new surplus inventory; original packaging may show signs of storage or handling. Condition is not inferred from the photograph, date code, packaging, or marketplace history.
- Does the original manufacturer warranty apply?
- We do not represent that a manufacturer warranty transfers with these motors. Our return terms and seller representations are set out on the Shipping & Returns page and in our Terms of Sale.
