Overview
The Model 5812 is a compact, highly reliable AC shaded pole motor engineered for low-power, continuous-duty ventilation and airflow applications. Utilizing the simple and robust shaded pole principle, this motor delivers maintenance-free operation in a miniature form factor, making it an ideal choice for compact appliances and devices requiring dependable, low-cost air movement.

Key Features & Advantages

• Compact & Lightweight Design: The compact 58mm frame size makes it ideal for integration into space-constrained devices where efficient air movement is critical.

• Inherently Reliable & Simple: The shaded pole design features no brushes, capacitors, or centrifugal switches. This single-phase induction motor design minimizes failure points, ensuring long service life with zero maintenance.

• Continuous Duty Capable: Rated for 100% duty cycle (S1), perfect for applications requiring constant, uninterrupted operation such as cooling or ventilation.

• Quiet & Smooth Operation: Engineered for low mechanical and magnetic noise, contributing to a quieter end-user experience.

• Cost-Effective Solution: Offers one of the most economical and reliable drive solutions for low-torque, constant-speed fan and blower applications.

• Easy to Control: Operates directly from a single-phase AC power source. Speed can be reduced (within a limited range) using simple voltage regulation techniques if required.

Typical Specifications

• Motor Type: Single-Phase AC Shaded Pole Induction Motor.

• Frame Size: 58mm (approximate flange or mounting dimension).

• Input Power: AC 100-120V / 220-240V, 50/60 Hz (specific model dependent).

• Output Power: Low power range, typically 3W to 15W.

• Synchronous Speed: 3000 RPM (50Hz) or 3600 RPM (60Hz). Actual operating speed is lower due to slip.

• Mounting: Versatile options including resilient rubber mounting studs, face-mounted flanges, or base mounts to minimize vibration transmission.

• Thermal Protection: Optional integrated thermal cut-off (TCO) for overheat protection.

• Shaft: Standard output shaft designed for secure attachment of axial fans, centrifugal blower wheels, or impellers.

Primary Applications
This motor is the driving force behind essential cooling and ventilation in compact appliances and equipment:

• Equipment Cooling: Internal fans for power supplies, projectors, AV equipment, networking devices, and gaming consoles.

• Appliance Ventilation: Small range hoods, microwave oven cavity cooling fans, ventilation fans for appliances.

• Air Purification & Humidification: Drive motors for small air purifiers, personal fans, and humidifiers.

• Commercial/Medical Devices: Cooling fans for point-of-sale systems, medical diagnostic equipment, and laboratory instruments.
