Gear Motor Requirements

Knowing the requirements of the gear motor for your application is very important before you embark on it. When you choose the correct type of motor, its potential and efficiency can be maximised.

For small DC geared motors, the requirements could be the following:
General: Lubrication type, overhung loads, side loads, mounting type, mounting orientation and envelope size.
Environment: The ingress protection rating, the ambient and application temperature need to be taken into consideration.
Input power: What should be the frequency, voltage, maximum current and control type?
Gear motor specifications: Take into account the weight of the motor, its size, maintenance level, noise level and life expectancy.
Gear motor performance: The torque, speed, horsepower, duty cycle and even the starting and stall torque matter.
Choose the correct gear motor

Once you have compared your list of requirements with the specifications and features of different small DC geared motors and motors like universal, induction, brushless and permanent magnet motors, you will have a basic idea of which one/ones you need. Such motors can be found at Teco Electric Co. Ltd. where you can match the pull-up torque, yield strength and performance curves to the gear motor.

When you pick the gear motor, see if it has the right speed and torque. The manufacturer’s performance curves can be used to check if a gear motor has the necessary speed, torque and efficiency. After comparison of a few performance curves with respect to yield strengths, pull-up torques etc., you can look into a few design specifications to make a shortlist of your choices.

Even after you have chosen the AC or DC gear motor that suits your applications, it is better to run a few tests to ensure its smooth functioning. It should not get too noisy, stressed or hot which would be bad news for the motor.
