2025 ICE Maker Auger Motor Solution – BLDC Outrunner Motor and Gearbox

Jiaming CaiMay 9, 2025

In commercial and smart home ice makers, the ice maker motor’s stability, noise, and lifespan play a key role in the user experience. To meet these requirements, Doncen Motor offers a compact gear motor solution with an integrated spur gearbox and a BLDC Outrunner motor. This design ensures high torque, low noise, and long service life, all in a space-saving structure—ideal for modern ice-making systems.

How to design Ice Maker Auger Motor

The main functions of the ice machine motor are ice mold rotation, ice pushing, ice breaking . Usually the Ice maker motor is required to have the following performance:

High Torque Output	Drives gears or pushrods for ice-breaking.
Low Noise	Under 40dB for quiet operation in home use.
Long Service Life	Supports 24/7 commercial use.
Compact Structure	Saves space inside the ice maker.
Moisture Resistance	Withstands humid, icy environments.
Low Temperature Resistance	Uses grease rated for sub-zero operation.

2025 Ice Maker Motor Solution – BLDC Outrunner Motor + Spur Gearbox

The mainstream solution for ice maker motors has traditionally been an AC shade pole motor combined with a spur gear reduction mechanism. However, an increasing number of household ice makers are now adopting brushless DC outer rotor motors as their core drive system, offering improved efficiency, quieter operation, and greater control.

Power Supply	AC input (110V / 220V)	DC input (12V / 24V)
Control	Basic ON/OFF	PWM speed control
Structure	Simple and low-cost design	Flat Design,More small
Startup Performance	Low starting torque, prone to stalling	High starting torque with fast response
Noise	High mechanical and electromagnetic noise	Low operating noise
Service Life	Limited lifespan, often maintenance-prone	Long lifespan, ＞5000H working life

Doncen Ice Auger Motor Design Advantages

Full In-house Production
Doncen manufactures both the brushless outrunner motors and the gearbox systems entirely in-house. This enables strict quality control, reduces defect rates, and ensures consistent production stability.
All-metal Gears
We use high-durability metal gears throughout the reduction stages. The last two stages are specially thickened to significantly enhance wear resistance and extend the gearbox lifespan, even under continuous load.
High Gear Ratios
Tailored for auger motion in ice makers, our gearboxes can achieve gear ratios from 1:150 to 1:600, providing high torque output while maintaining compact dimensions.
Best Price Match
With full control over both motor and gear production, we deliver reliable quality at a competitive price, offering the best value for manufacturers seeking durable and efficient drive systems.

Applications of Ice Maker Motor

Currently our Ice Maker Motor is used in some home ice makers and commercial ice makers.
