Overview
The Outer Runner Capacitor Motor is an innovative, high-efficiency motor solution engineered specifically for blower and centrifugal fan applications. Featuring a unique design where the rotor (the "runner") rotates externally around a stationary internal stator, this motor is combined with a capacitor-run (PSC) system to deliver powerful, stable, and smooth airflow with enhanced durability and ease of integration. It is an ideal choice for demanding ventilation, HVAC, and air movement systems.
Key Features & Advantages
High Torque & Direct Drive Capability: The outer runner configuration inherently provides high torque at startup and low speeds. This allows the motor to be directly coupled to the blower wheel or impeller, eliminating the need for belts, pulleys, or additional reduction gears, simplifying the system and improving reliability.
Excellent Heat Dissipation: The external rotor design exposes the motor's rotating shell to the airflow, creating a natural and highly effective self-cooling mechanism. This results in lower operating temperatures, which enhances motor longevity and allows for higher continuous power output.
Compact & Integrated Design: The motor is built into a single, compact unit that often incorporates the blower housing or mounts directly to it. This space-saving design is perfect for applications where a streamlined, all-in-one air movement module is required.
Smooth & Quiet Operation: The permanent split capacitor (PSC) design provides a balanced two-phase power supply, leading to smooth rotation with minimal vibration and low electromagnetic noise. The external rotor's mass also contributes to rotational stability.
Energy Efficient: The combined efficiency of the capacitor-run design and the optimized magnetic circuit of the outer runner motor results in high overall electrical efficiency, reducing operational energy costs.
Robust & Low Maintenance: The construction is rugged, often featuring a sealed bearing system. With no brushes to wear out and the capacitor as the only primary electrical component, the motor is virtually maintenance-free for long-term, reliable service.
Versatile Speed Options: Easily configured for single-speed, two-speed, or three-speed operation through multiple winding taps, providing flexibility for different airflow requirements.
Typical Specifications
Motor Type: Outer Runner (External Rotor), Permanent Split Capacitor (PSC) Motor.
Construction: Stator is fixed centrally; the outer casing (rotor) rotates, carrying the fan blades or blower wheel.
Input Power: 115/230V AC, 50/60 Hz.
Power Range: Commonly from 10W to 250W for blower applications.
Speed: Often designed for direct drive at common blower speeds (e.g., 800 - 1500 RPM).
Capacitor: Integral run capacitor for continuous operation.
Mounting: Typically designed as a complete blower assembly or with a central mounting hub.
Airflow Direction: Can be configured for tangential (crossflow) or centrifugal airflow, depending on the integrated blower wheel design.
Primary Applications
This motor is exceptionally well-suited for applications requiring compact, powerful, and direct-drive airflow:
HVAC Equipment: Furnace blowers, air handler units, fan coil units, duct booster fans.
Air Purification & Conditioning: Commercial air purifiers, ERV/HRV cores, dehumidifier blowers.
Appliance Ventilation: High-power range hoods, dryer exhaust blowers.
Industrial Process Air: Oven circulation fans, cooling tunnel blowers, fume extractors.
Why Choose an Outer Runner Capacitor Motor for Your Blower?
For designers of air movement systems, this motor offers a superior integrated solution. It combines the simplicity and reliability of a capacitor-run motor with the mechanical and thermal advantages of an external rotor design. The result is a compact, powerful, cool-running, and quiet blower module that reduces assembly complexity, saves space, and delivers dependable performance year after year.

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.
