Capacitor Electric Motors
A capacitor electric motor is a type of single-phase induction motor that uses capacitors to improve starting torque, efficiency, and power factor. These motors are widely used in applications requiring reliable self-starting and smooth operation under load.
Capacitor-Assisted Operation
Starting Capacitor: Provides high torque at startup (disconnected after reaching speed via centrifugal switch).
Running Capacitor: Continuously improves efficiency and power factor during operation.
High Starting Torque
Ideal for heavy-load applications (e.g., compressors, pumps).
Improved Efficiency
Reduces reactive power loss compared to split-phase motors.
Low Maintenance
No brushes or commutators (induction motor design).
Capacitor-Start Motor: Uses a capacitor only during startup (high torque, then switches off).
Capacitor-Run Motor: Continuously uses a capacitor for smoother operation (e.g., fans, blowers).
Dual-Capacitor (Capacitor-Start/Capacitor-Run): Combines both for optimal performance (common in HVAC systems).
HVAC Systems (Air conditioners, compressors)
Industrial Machinery (Pumps, conveyors, lathes)
Household Appliances (Washing machines, refrigerators)
Agricultural Equipment (Water pumps, grain augers)
✔ 2–4x higher starting torque
✔ Quieter operation with reduced vibration
✔ Longer lifespan due to lower stator heating
✔ Better power factor (closer to 1.0)
Capacitor Sizing: Critical for phase-shifting the auxiliary winding current (typically µF range, e.g., 50–400 µF).
Failure Modes: Capacitor degradation (e.g., electrolyte drying) can cause humming or failure to start.

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.
