Overview
The 61 Series Micro Shaded Pole Motor is a specialized, ultra-compact AC induction motor engineered as the integral drive for miniature hermetic compressors. Designed for low-capacity, continuous-duty cooling applications, this motor leverages the inherent simplicity and durability of the shaded pole principle to provide reliable, maintenance-free compression in a minimal footprint. It is the core power source for micro-scale refrigeration and air circulation systems where space, efficiency, and reliability are critical.
Key Features & Advantages
Ultra-Compact & Integrated Design: The 61 Series frame represents one of the smallest standardized packages for shaded pole compressor motors, allowing direct integration into tiny hermetic shells. This enables the development of extremely compact cooling units for space-constrained devices.
Optimized for Low-Speed, High-Torque Compression: Specifically wound to provide optimal torque characteristics at low synchronous speeds (e.g., 1500/1800 RPM), delivering the necessary force to drive micro-pistons, diaphragms, or scroll mechanisms efficiently against system pressure.
Hermetic Environment Ready: Constructed with materials fully compatible with refrigerant and lubricating oil atmospheres. Features moisture-resistant, high-temperature insulation systems (Class F or higher) and varnishes that withstand long-term exposure inside a sealed compressor unit.
Exceptional Reliability & Long Life: The shaded pole design has no brushes, capacitors, or centrifugal switches. This brushless, self-starting architecture minimizes failure points, ensuring a long operational lifespan—often exceeding 20,000 hours—under continuous duty in sealed systems.
Smooth, Low-Vibration Start & Run: Provides gentle, inherent starting torque without electrical stress from high inrush currents. The shaded pole operation ensures smooth rotation, reducing mechanical vibration and noise within the compressor assembly.
Thermal Endurance: Engineered to operate reliably within the elevated temperatures and oil-rich environment of a micro-compressor. Utilizes high-temperature magnet wire and thermally stable components.
Cost-Effective Miniaturization: Offers the most economical and technically simple motor solution for achieving fixed-speed compression in micro-scale applications, keeping system costs low.
Typical Specifications
Motor Type: Single-Phase AC Shaded Pole Induction Motor.
Frame Series: 61 (Denoting a micro compressor motor package).
Input Power: AC 100-120V / 220-240V, 50/60Hz.
Synchronous Speed: 1500 RPM (50Hz) or 1800 RPM (60Hz) for 4-pole design.
Output Power: Very low power range, typically 3W to 15W, suitable for micro-compression duties.
Torque Profile: Designed for reliable start-up against back pressure and stable running torque.
Integration: Designed for direct press-fitting, welding, or epoxy potting into miniature compressor housings.
Thermal Protection: Can be customized with internal thermal cut-off devices for overheat protection.
Primary Applications
This micro motor is the driving heart of miniaturized cooling systems:
Mini/Micro Refrigeration: Cooling units for mini fridges, wine coolers, dehumidifiers, medical sample storage, and laboratory chillers.
Portable Cooling Devices: Personal air coolers, beverage dispensers, electronic enclosure coolers.
Specialized OEM Systems: Cooling for laser equipment, projectors, analytical instruments, and vending machines.
Low-Capacity Air Conditioning: Micro-split systems or components.
Why Choose the 61 Series Micro Shaded Pole Motor for Compressors?
For designers of miniaturized cooling systems, the 61 Series solves the critical challenge of integrating reliable mechanical power into an extremely small volume. Its ability to provide direct, low-speed drive eliminates the need for bulky external gear reduction, simplifying compressor design. Its legendary simplicity and ruggedness ensure the core of your micro-cooling system operates silently and reliably for years, making it the trusted electromechanical solution for compact, dependable thermal management.
