Main Applications
Kitchen & Food Equipment
BBQ rotisserie drives, fireplace mechanisms, meat choppers, western kitchen equipment, restaurant equipment, and other fixed-AC low-speed transmission mechanisms.
Focus: Suitable for fixed-speed, cost-sensitive designs. Confirm load, temperature rise, grease condition, and continuous operating time in the complete machine.
Commercial & Vending Equipment
Vending machines, beverage equipment, coffee machines, dispensing mechanisms, and other unattended AC-powered low-speed drives.
Focus: Verify restart performance, jam/stall conditions, long-term operation, ambient temperature, and thermal protection under the actual duty cycle.
Air Treatment & Appliance Equipment
Air cleaners, ventilation-related mechanisms, auxiliary fan drives, and other appliance mechanisms requiring stable low-speed output from fixed AC power.
Focus: Noise, temperature rise, fan loading, bearing configuration, and enclosure ventilation should be validated in the finished product.
Agricultural & General Equipment
Agricultural equipment, instruments, simple rotating mechanisms, and other light- to medium-duty machines with available AC power.
Focus: For dusty, humid, or outdoor-adjacent installations, system-level protection against moisture, dust, corrosion, and insulation degradation is required.
Custom OEM Equipment
OEM mechanisms requiring a 70 × 122.5 mm-class gearbox face, selectable motor length, customized output shaft, or project-specific voltage, speed, and torque matching.
Focus: Final suitability should be confirmed from the actual load, installation space, duty cycle, ambient conditions, and required service life.
Customization Range
Electrical Configuration
AC100V–240V, 50Hz–60Hz; winding configuration, rotation direction, lead wire, and terminal options can be evaluated according to the project.
Performance Matching

Mechanical Interface
Output shaft size and geometry can be customized; motor length is available in multiple GM70B variants, and a ball-bearing configuration is specified for matching.
Thermal & Protection
Validate temperature rise, stall/overload, restart, continuous operating time, and heat dissipation in the complete product; thermal protection can be evaluated where required.
Noise & Reliability
Optimize magnetic noise, fan/bearing noise, gear meshing, lubrication, mounting resonance, and batch consistency according to the complete equipment.
FAQ
Q1. Can an AC shaded pole gear motor run continuously for long periods?
Yes, continuous operation can be designed for, but the actual operating load, winding temperature rise, ambient temperature, heat dissipation, bearing or sleeve life, and lubrication conditions all need to be evaluated.
Continuous-duty and thermal testing should therefore be carried out in the complete product, and thermal or overload protection may be required depending on the application.
Q2. How can noise and vibration be reduced in an AC shaded pole gear motor?
Noise and vibration should be optimized at both the motor and gearbox levels. Key factors include the magnetic design and winding, rotor balance, bearing or sleeve condition, gear accuracy, gear backlash, gear material, lubrication, and the mounting structure.
The fan blade, product housing, and mounting bracket can also introduce resonance. For this reason, noise should be evaluated in the customer’s actual product, including start-up noise, running noise, gear-meshing noise, and structural resonance, rather than relying only on no-load motor noise.
Q3. How can reliability be improved under stall, overload, or voltage fluctuation conditions?
The motor should be evaluated under actual operating conditions, including stall current, winding temperature rise, starting capability, and restart performance. For equipment that may experience jamming, blocked fan blades, or prolonged overload, thermal protection, fuses, overload protection, or control-system protection should be considered.
Testing should also cover low-voltage starting, high-voltage temperature rise, stalled operation, power-loss restart, and restart after long periods of inactivity to ensure that changes in supply voltage or frequency do not push speed, torque, or temperature beyond the acceptable operating range.
Q4: What information should I provide for a faster quotation and technical evaluation?
Please provide the operating voltage, torque, and target speed. If complete parameters are not available, an existing motor sample, prototype, or mechanism drawing can be used for initial evaluation.
