Delco Fans manufactures robust AC Shaded Pole Geared Motors designed to provide controlled output speeds, boosted mechanical torque, and dependable performance in continuous-duty applications. By pairing a proven single-phase shaded pole electric motor with a precision gearbox housing brass and hardened metallic gears, these drive units ensure smooth power transmission with quiet acoustic signatures.
Built in our Thane manufacturing plant since 1974, every unit is engineered to satisfy rigorous international OEM standards for thermal rise, mechanical endurance, and dimensional consistency.
Engineered specifically for low-speed mechanical activation, our geared motors combine long continuous service life with high torque-to-frame ratios.
Helical and spur gear combinations crafted from high-grade brass and steel alloys to guarantee minimal gear wear and high torque transfer efficiency.
Precision-machined tooth profiles and acoustic damping keep operational noise low, ideal for medical, office, and commercial environments.
Permanently lubricated gearboxes paired with Class B or Class F insulated copper windings ensure non-stop performance without re-greasing.
Optional integrated thermal cutoffs protect windings from electrical surges, stalled-rotor conditions, and extreme ambient heat stress.
Optimized inline gear housing delivers high output torque without requiring excessive mounting depth inside compact machine enclosures.
Simple single-phase AC design eliminates complex electronic controllers while providing reliable starting and operating torque curves.
Baseline engineering options available for volume production. Custom shaft dimensions, gear ratios, and mounting brackets can be engineered to order.
