How to technically select a DSK gear motor

When selecting a DSK gear motor, one should not rely solely on motor power. A suitable model must be calculated based on the entire drive requirements of the machine.

1. Determine motor power

Motor power is typically selected based on the actual load of the machine. Common ratings can range from 0.2 kW, 0.4 kW, 0.75 kW, 1.5 kW, 2.2 kW, 3.7 kW, 5.5 kW to 7.5 kW depending on the product line and application.

2. Select gear ratio

The gear ratio determines the output speed of the gearbox. The higher the gear ratio, the lower the output speed and the higher the torque. For example, a 1:10 gear ratio provides a higher output speed than 1:50, but with lower torque.

3. Check output torque

Torque is a critical parameter. If the torque is insufficient, the gear motor may overheat, overload, cause premature gear failure, or fail to pull the load. For conveyor belts, agitators, or crushers, an appropriate safety factor should be applied.

4. Select mounting type

It is necessary to determine whether the gear motor requires foot mounting, flange mounting, parallel shaft, right-angle shaft, hollow shaft, or solid shaft. Choosing the wrong mounting type may result in the equipment not fitting the existing machine.

5. Check the operating environment

If the motor operates in dusty, humid, high-temperature, heavy-load environments, or under continuous operation, it is necessary to select the correct protection class, insulation class, and appropriate service factor.
