A DC gear motor features the same basic motor design as a DC motor but also includes a gearbox to create a single motion control component. This design allows speed reduction while increasing torque output in electromechanical applications.


A DC motor and DC gear motor are both manufactured with a brushed or brushless motor and feature either a standard or coreless design. They are compact, cost-effective and used in applications ranging from vending machines to robotics equipment. The two most prominent types of gear motors are planetary and spur gear motors.


Gear Motor Specs
Voltage: Do you need AC or DC voltage? What voltage do you need your motor to run at?
Speed (RPM): Does the application have high or low speeds? Are the speeds continuous or varying?
Power (W): What are your wattage requirements? If using a control, do you have amperage limitations?
Torque (in-lb or Nm): Do you need high start or stall torque? What are your running torque requirements?
Duty Cycle: Will your motor be operating continuously or in short bursts with time to cool down in between?
Life Expectancy: How long of a life does your motor need (expressed in cycles)?
Frequency: Do you need to operate at 60 Hz, 50 Hz or both 50/60 Hz?
Current (Efficiency): Does the overall efficiency or current draw need to be under a certain value?
Control: Will your application need to vary speeds? What type of control will you need?
