Overview
The CW/CCW Synchronous Motor is a versatile, bi-directional AC synchronous motor engineered for precise, constant-speed applications in appliances and electronic instruments. Designed to operate with equal efficiency in both clockwise (CW) and counterclockwise (CCW) rotation, this motor provides reliable, low-speed torque for driving circulation fans in dishwashers, as well as for timing mechanisms, actuators, and motion control in sensitive electronic equipment.
Key Features & Advantages
Bi-Directional Constant Speed Operation: Engineered to provide identical performance characteristics—including torque, speed, and power—in both rotational directions. Speed remains perfectly synchronized with the supply frequency regardless of direction, ensuring consistent timing or airflow performance.
Precise Low-Speed Torque: Delivers stable, high torque at low synchronous speeds (e.g., 250 RPM, 500 RPM), making it ideal for direct-drive applications where gear reduction is undesirable, such as gentle air circulation or slow, precise mechanical indexing.
Quiet and Vibration-Free Performance: The synchronous operation and precision-balanced rotor ensure exceptionally smooth and quiet running, which is critical for residential appliances like dishwashers and for sensitive laboratory or medical instruments.
Simple Direction Control: Rotation direction can be easily selected by switching the connection of the motor's main and auxiliary windings via a simple external relay or switch, enabling flexible control logic in automated systems.
High Reliability & Maintenance-Free Design: As a brushless AC motor with no capacitors for running (in a reluctance or hysteresis type), it offers a long operational lifespan with zero maintenance—perfect for sealed or hard-to-access installations in appliances.
Compact and Lightweight: Designed with a focus on space efficiency, allowing for easy integration into the tight confines of dishwasher sump areas, instrument panels, or compact device housings.
Thermally Resilient: Built to withstand humid, warm environments such as those found in dishwashers, with materials resistant to moisture and detergent vapors.
Typical Specifications
Motor Type: Single-Phase AC Synchronous Motor (Reluctance or Hysteresis type common).
Rotation: Reversible (CW/CCW) with external switching.
Supply Voltage: 120V AC or 230V AC, 50/60 Hz.
Synchronous Speed: Common low speeds: 250 RPM, 300 RPM, 500 RPM (at 50Hz).
Output Power: Low to moderate, typically 3W to 20W.
Mounting: Standardized flange or bracket mounts for secure installation.
Shaft: Configured for direct mounting of small centrifugal fan impellers or coupling to instrument drives.
Protection: Often totally enclosed or treated for resistance to mild moisture and splashes.
Primary Applications
Dishwasher Circulation/Drying Fans: Provides bi-directional airflow for optimal water circulation during wash cycles and efficient air movement during the drying phase.
Electronic Instruments: Drives for chart recorders, plotters, sequencing timers, rotary switches, and optical scanning mechanisms.
Office Automation: Document feeders, scanner drives, precision paper advance mechanisms.
Ventilation & Dampers: Small damper actuators in HVAC or appliance ducting requiring reversible action.
Why Choose This CW/CCW Synchronous Motor?
For designers of appliances and precision instruments, this motor solves the dual need for directional flexibility and unwavering speed accuracy. Its ability to deliver identical performance in both directions eliminates the complexity of using two different motors or complex mechanical reversers. Whether ensuring even drying in a dishwasher or precise paper advance in an instrument, it offers a simple, reliable, and quiet solution for controlled bidirectional motion.
Typical used: Exhaust fan, air purifier, micro-oven, fan, induction cooker, refrigerator, pump, heater, hood oven, blwer, air conditioner, Heater machines, dehumidifiers

Our company FAQ for you
(1) Q: What kind motors you can provide?
A:For now,we mainly provide Kitchen Hood Motor,DC Motor,Gear Motor,Fan Motor Refrigerator Motor,Hair Dryer Motor Blender Motor Mixer Motor,
Shade Pole Motor,Capacitor Motor,BLDC Motor PMDC Motor,Synchronous Motor,Stepping Motor etc.
(2) Q: Is it possible to visit your factory
A: Sure. But please kindly keep us posted a few days in advance. We need to check our
schedule to see if we are available then.
(3) Q: Can I get some samples
A: It depends. If only a few samples for personal use or replacement, I am afraid it will
be difficult for us to provide, because all of our motors are custom made and no stock
available if there is no further needs. If just sample testing before the official order and
our MOQ, price and other terms are acceptable, we'd love to provide samples.
(4) Q: Is there a MOQ for your motors?
A: Yes. The MOQ is between 1000~10,000pcs for different models after sample approval.
But it's also okay for us to accept smaller lots like a few dozens, hundreds or thousands
For the initial 3 orders after sample approval.For samples, there is no MOQ requirement. But the less the better (like no more than 5pcs) on condition that the quantity is enough in case any changes needed after initial testing.
