Shaded Pole Motors for Small Appliance Duty
Shaded pole motors are the simplest, most economical way to drive small fans, blowers and light appliance mechanisms — and a standard line in Nanyang’s appliance motor range. This page is deliberately honest about two things: what a shaded pole motor is good at, and the fact that this line is specified per project rather than from a published model table.
- Model data
- Not published in the company catalogue
- Specification
- Confirmed per project, in writing
- Drawings / samples
- Availability confirmed per enquiry, in writing
This line is assessed project by project. Send your equipment drawings and duty data; the reply assesses feasibility first, and any specification, drawings, samples or pricing follow that assessment, in writing.
01 The Technology
Why buyers still choose shaded pole
A shaded pole motor is a single-phase induction motor with a short-circuited copper shading coil set into part of each stator pole. That shaded section delays the magnetic field, creating the rotating component that starts the motor — no starting capacitor, no centrifugal switch, no electronics. The result is a motor with very few failure points, tolerant of stall and voltage variation, and cheap to build at volume. The trade-offs are equally well known: modest starting torque and lower efficiency than capacitor-run designs. For a fan that starts unloaded and runs for hours, that trade is usually right. For a load that must start against resistance, it usually is not — our guide to capacitor start vs capacitor run motors walks through the decision.
Typical shaded pole duties in appliances include ventilation and exhaust fans, fan-coil and refrigeration display fans, small blowers, and light mechanisms where the load is aerodynamic rather than mechanical. Our companion article on shaded pole motor applications lists where the type earns its keep and where to step up to a capacitor motor instead.
02 Specifying
What to send for the assessment
Because this line carries no published model table, feasibility is assessed from your specification first. The checklist below is what the works will ask — sending it up front shortens the exchange to one round:
- Duty: the appliance and load type (fan curve if it is a blower), and whether the load starts unloaded
- Electrical: rated voltage (the company’s catalogue motors are wound for 220–240 V or 110 V), frequency 50 or 60 Hz, and target speed
- Mechanical: shaft diameter and length, mounting style and fixing centres, direction of rotation viewed from the shaft end
- Environment: ambient temperature, humidity or splash exposure, and any insulation class your market’s rules require
- Programme: estimated quantity per shipment and per year, and whether a sample stage is needed before tooling decisions
Nanyang’s company profile describes a works organised in three plants, one of them dedicated to washing machine and grinder motors, and an official range that runs from shaded pole units to BLDC solutions. A buyer consolidating several small-motor lines — fans here, wash motors there — can put the whole basket into one enquiry and one shipment.
03 Questions
Shaded pole, answered plainly
Why is there no model table on this page?
Because the company has not published one for this line, and we will not invent one. The nine models with full published data are in the catalogue. For shaded pole motors, send your specification with the enquiry; feasibility is assessed against it first, and the reply states whether a data sheet can be issued for it and what it would still need.
Shaded pole or capacitor motor — which do I need?
If the load is a fan or blower starting unloaded, shaded pole is normally the economical answer. If the load must start under torque — a pump, a compressor mechanism, a loaded drum — step up to a capacitor design. The applications guide gives worked examples.
Can the motor be wound for my market’s voltage?
State your market’s nominal voltage and frequency in the enquiry, with the duty and specification from the checklist above. Whether a winding for that rating can be supplied for this line is assessed per project, and the reply after that assessment states whether it can be done or cannot be done — neither outcome is assumed in advance.
Send the duty for assessment
One email with the checklist above is enough to start. The reply assesses feasibility for your exact shaded pole requirement first, and states what specification and price can be confirmed and what further inputs are needed — not a near-enough catalogue substitute.
