By Gear Type
Spur Gear DC Brush Motor
- Uses simple straight-cut gears.
- Cost-effective and efficient.
- Common in toys, vending machines, and small appliances.
Planetary Gear DC Brush Motor
- Uses planetary gear sets (sun, planet, ring).
- Offers higher torque, compact size, and better durability.
- Used in robotics, industrial drives&automation.
Worm Gear DC Brush Motor
- Uses a worm screw and gear.
- Provides high torque, low speed, and self-locking ability.
- Used in lifts, gates, and medical equipment.
By Gear Material
Metal
- Metal gear motors have high strength and durability.
- Handles higher torque loads.
- Longer lifespan under continuous or heavy-duty use.
- Better resistance to wear and heat.
Plastic
- Plastic gears wear faster under load.
- More affordable and lightweight.
- Quieter operation due to softer gear contact.
- Suitable for low to moderate torque applications.
By Shaft Type
Single Shaft
- Most common type.
- One output shaft on one end of the motor.
- Ideal for general applications where you only need to drive one mechanism.
Dual Shaft
- Has two output shafts: one on each end of the motor.
- Adding an encoder to one shaft for feedback control.
- Driving two mechanisms simultaneously.
- Balancing or symmetrical mechanical designs.
Combination Options
With Encoder
- Provides feedback on speed and position.
- Use Case: Ideal for closed-loop control, robotics, and automation.
- Benefit: Enables precise motion control and positioning.
- Usually has a rear-mounted rotary encoder (optical or magnetic).
With Wheel
- Motor pre-attached to a wheel.
- Common in robotic cars, AGVs, and DIY mobile platforms.
- Saves assembly time, optimized for traction.
- Includes a rubber/plastic wheel mounted on the shaft.
With Brake
- Halts and holds motor position when power is turned off.
- Ideal for elevators, electric locks, lifting systems.
- Prevents back-driving or unwanted movement under load.
- Electromagnetic brake mounted to the motor.
With Controller
- Comes with an integrated or matched control board.
- Used in systems needing plug-and-play control (e.g., speed, direction).
- Simplifies setup and reduces need for separate driver.
- Often includes PWM input or adjustable speed knob.

FAQ
1.What are a DC brushed gear motor's primary parts?
Motor housing, brushes, commutator, rotor (armature), stator, and gearbox.
2.What use does a gear motor's gear serve?
To boost torque output and decrease motor speed in heavy-duty applications.
3.What is the torque range of brushed gear motors?
It varies widely — from a few mNm for mini motors to several Nm for industrial ones.
4.How fast can a DC brushed gear motor spin?
Speeds range from <10 RPM (high torque) to >1000 RPM (low torque), depending on gear ratio.
5.How do I connect a DC brushed gear motor?
Connect the motor's two terminals to a DC power supply or motor driver module.
6.Can I use an H-bridge to control a brushed gear motor?
Yes, an H-bridge lets you control direction and speed efficiently.
7.Do DC gear motors need a driver?
For basic operation, no — but for PWM control or direction reversal, a motor driver is recommended.
