Ritscher
The 72 Series shaded pole motor is a compact, single-phase induction motor known for its simple construction, reliability, and cost-effectiveness. It utilizes a shaded pole (a short-circuited copper coil) to create a rotating magnetic field, enabling self-starting without capacitors or additional windings.
✔ Simple & Durable Design
No brushes, capacitors, or centrifugal switches → minimal maintenance.
Robust construction with a laminated stator core and shading rings.
✔ Low Starting Torque but Smooth Operation
Ideal for low-power applications requiring consistent, vibration-free performance.
✔ Quiet & Energy-Efficient
Low electromagnetic noise (<40 dB) → suitable for household appliances.
Operates at 50/60 Hz with moderate efficiency (typically 15-30%).
✔ Cost-Effective
Fewer components → lower manufacturing cost than capacitor-start motors.
| Parameter | Typical Range |
|---|---|
| Power Rating | 1W to 25W |
| Voltage | 100-240V AC (50/60 Hz) |
| Speed | 1500-3000 RPM (4/6-pole) |
| Torque | Low (sufficient for light loads) |
| Efficiency | 15-30% (lower than PSC motors) |
| Noise Level | <40 dB |
Household Appliances (Fans, humidifiers, coffee grinders)
HVAC Systems (Small blowers, exhaust fans)
Office Equipment (Projectors, document shredders)
Medical Devices (Air purifiers, small pumps)
✅ Pros:
Extremely reliable with long lifespan.
Simple and low-cost manufacturing.
No need for a starting capacitor or switch.
❌ Cons:
Low starting torque (not suitable for heavy loads).
Lower efficiency compared to capacitor-run motors.
Limited speed control options.
| Feature | Shaded Pole Motor | PSC Motor | Capacitor-Start Motor |
|---|---|---|---|
| Starting Torque | Low | Medium | High |
| Efficiency | Low (15-30%) | Medium (50-65%) | Medium-High (60-75%) |
| Cost | Very Low | Moderate | Higher |
| Maintenance | Minimal | Low | Moderate (capacitor wear) |
The 72 Series shaded pole motor is a cost-effective, reliable solution for low-power, continuous-duty applications where simplicity and quiet operation matter more than high torque or efficiency.
Typical used:
Hospital nebulizer, Exhaust fan, air purifier, micro-oven, fan, induction cooker, refrigerator, pump, heater, hood oven, blwer, air conditioner, Heater machines, dehumidifiers
Thermal protector with one shot fuse or multi shot fuse
Shaft diameter(mm)=4-6mm
Shaft length(mm)=according to customer's requirement
Speed(r/min)=according to customer's requirement
Current(A)=according to customer's requirement
Input power(W)=according to customer's requirement
