AC induction gear motor is an integrated ac induction gear motor combining induction drive and reduction gear module. It inherits the stable performance of asynchronous induction motors with precision reduction assembly, delivering steady torque and controllable speed. Widely applied in conveyor rollers, rotary fixtures, sorting lines and food processing machinery for fixed reduction drive.
Low-harmonic stator winding design
Optimized short-pitch winding reduces harmonic loss. This ac induction gear motor generates less electromagnetic interference and has minimal impact on nearby sensors and precise electronic controls.
Graded load-bearing gear structure
The gear set adopts graded load distribution to spread stress evenly and avoid stress concentration at single points, improving gear durability during heavy-load startup.
Pressure balance structure for separate oil chamber
A breather valve is built into the gearbox to balance internal pressure with temperature change. It prevents water ingress under negative pressure and oil leakage under positive pressure for reliable long-term sealing.
Product advantages
Stable speed within wide rated load range
Speed drop is limited within rated load range. Output speed stays consistent under minor load fluctuation, ideal for production lines requiring uniform conveying speed.
Auxiliary heat dissipation channel for bearings
Extra cooling passages on the bearing housing accelerate heat dissipation, slow grease degradation and extend the bearing maintenance interval of the ac induction gear motor.
Detachable terminal compartment
Independent removable terminal box. You can wire, rewire or inspect windings without disassembling the gearbox for simpler maintenance.
Q: Can the ac induction gear motor run long-term under intermittent shock load?
A: It tolerates intermittent shock load, yet the peak shock torque should not continuously exceed 2.2 times rated torque. Overload protection is recommended for frequent shock applications.
Q: What problems will a blocked breather valve cause to the AC induction gear motor?
A: A blocked breather valve leads to unbalanced internal pressure, which easily causes oil seepage or moisture suction. The breather valve needs regular cleaning.
Q: Can the gears of this ac induction gear motor be upgraded to different materials?
A: Custom stainless steel or wear-resistant alloy gears are available to replace standard carbon steel gears for corrosive or high-abrasion environments.
Q: What is the key selection difference between ac induction gear motor and DC geared motor?
A: The ac induction gear motor runs directly on AC mains without extra DC power supply. DC geared motors require DC power source but feature faster speed response.
Q: Will the gear noise of the ac induction gear motor increase obviously when running at low VFD speed?
A: Electromagnetic noise reduces at low VFD speed while gear meshing frequency changes. This ac induction gear motor adopts tooth profile modification to limit noise rise. Silent gear version is available for ultra-low speed heavy load applications.
