If your required torque exceeds the rated torque of the gearmotor, it can negatively affect the design life (see sidebar). Talk to one of our application engineers about design life estimates. Gearhead life depends on output torque, start/stop frequency, shock loads, operating speed, actual load and operating temperature. When choosing a gearmotor for a specific application, consider the rated (max) speed and available torque that are listed on the gearbox’s nameplate. Gearboxes reduce motor speed and multiply torque. Once the duty cycle of the application has been determined, the two most important specs are desired speed and torque. If the application requires a gearmotor for continuous duty operation, then choose one with a torque rating that is higher than the expected application torque. It will require less mounting space, and likely will be the most cost-effective solution. If the gearmotor will operate for only a few minutes or hours per day, consider the peak torque rating, and select the smallest gearmotor available. Selecting the Right Gearmotor Consider these basic design criteria to determine which gearmotor is right for your application.
