If you are unsure which parallel shaft gear motor model you need, follow these steps to ensure proper selection and reliable operation.
Step 1 – Determine Required Speed and Gear Ratio
Identify the operating speed of your machine. Then calculate the reduction ratio of the gear motor based on the required output speed:
Reduction Ratio = Motor Speed ÷ Required Machine Speed
- Example: If the motor is 1500 rpm and the machine needs 100 rpm, the ratio ≈ 1500/100 = 15:1.
- Choose a standard ratio close to your calculation (e.g., 15, 20, 25…).
Step 2 – Calculate Load Torque and Select Motor Output
Estimate the torque required at the output shaft considering load type, duty cycle, and safety margin (typically 1.2–1.5×).
- Select a reducer and motor combination whose rated output torque and power meet or exceed your requirement.
- Confirm the matching three-phase asynchronous motor (voltage, frequency, efficiency class, insulation, IP rating).
Step 3 – Confirm Additional Functions
Check whether your application needs any of the following options:
- Brakes: power-off brake / power-on brake
- Speed Control: inverter (VFD) or fixed-speed version
- Mounting & Frame: special frame size, hollow/solid shaft, keyway, flange
- Environment: low temperature, high humidity, food-grade, or other special conditions
Confirm these features with our technical team before ordering so we can produce to your exact requirements.
