How to select the appropriate GGM geared motor

To select the correct GGM Geared Motor, the following information must be fully determined:

1. What is the application?

2. What is the required load weight?

3. What is the desired output speed in rpm?

4. What is the required torque?

5. Is the power supply AC or DC?

6. Is an AC, DC, or BLDC motor required?

7. What type of gearhead is needed?

8. What is the desired gear ratio?

9. What is the required output shaft type?

10. What is the mounting style on the machine?

11. Is a controller required?

12. Is a brake required?

13. Is an encoder required?

14. Does the motor run continuously or intermittently?

15. What is the start/stop frequency?

16. Is the installation space limited?

17. Is the operating environment subject to dust, moisture, water, oil, or high temperatures?

18. Is it necessary to replace an old model?

Do not select a GGM motor based solely on power (W). For geared motors, it is necessary to simultaneously check the power, speed, gear ratio, output torque, and the load capacity limit of the gearhead.

Notes on selecting a GGM gearhead

The gearhead is the component most prone to incorrect selection in a small geared motor assembly. If the gearhead is under-rated for the load, the machine may run initially but will quickly become noisy, overheat, or develop shaft backlash.

It is necessary to carefully check:

• Permissible torque

• Service factor

• Overhung load

• Thrust load

• Gear ratio

• Output speed

• Load position on the shaft

• Drive type using pulleys, sprockets, gears, or belts

• Daily operating hours

• Reversing frequency

• Start/stop frequency

If the gearhead output shaft is equipped with pulleys, sprockets, or gears, the radial load must be checked. If the load is placed too far from the shaft end or the pulling force is too high, the bearings and output shaft may fail prematurely.

Common mistakes when selecting a GGM Geared Motor

Selecting solely based on power (W)

A 60W, 90W, or 120W motor does not fully indicate the load-pulling capability. It is necessary to additionally check the output speed, gear ratio, and torque.

Selecting the wrong gear ratio

A gear ratio that is too low results in an output speed that is too high and insufficient pulling force. A gear ratio that is too high results in a speed that is too slow and may not be suitable for the machine cycle.

Not checking the permissible torque of the gearhead

The gearhead has its own torque limit. If this limit is exceeded, the gearbox may become noisy, overheat, wear out, or fail.

Selecting the wrong AC, DC, or BLDC motor

If the machine requires smooth speed control but a simple AC motor is selected, it may not be optimal. If the machine only runs at a fixed speed but a BLDC motor is selected, it may lead to unnecessary costs.

Ignoring the controller

BLDC motors require a driver. Speed Control Motors require a controller. You cannot select a motor while ignoring the appropriate control unit.

Not checking the installation space

Automated machines often have limited space. It is necessary to check the motor length, shaft orientation, wire position, gearbox, and clearance during installation.

Signs of incorrect GGM geared motor selection

Some common signs when selecting the wrong motor or gearhead:

• Motor overheats quickly

• Gearhead makes loud noise

• Machine runs weakly

• Incorrect speed

• Motor cannot pull the load

• Driver reports overcurrent error

• Output shaft has backlash

• Gearbox wears out quickly

• Machine runs jerkily

• Unstable speed

• Motor does not fit the installation space

• Incompatible with controller

When encountering these issues, it is necessary to re-check the load, speed, gear ratio, torque, power supply, motor type, controller, and mechanical installation method.
