To determine
Explain the reason for the usage of gear motors in many industrial machines, instead of low rpm induction motors.
Expert Solution & Answer
Explanation of Solution
Discussion:
The reasons for the usage of gear motors in many industrial machines instead of low rpm induction motors are as follows:
- The gear motor is a machine which provides a direct power drive from a single unit and it is a speed reducing machine.
- The gear motors are extremely small size and provide efficient power drive. The low-speed induction motors are heavy, large in size, and very expensive for the same horse power as gear motors.
- The gear motors are available in different types of standard motors. For example, the gear motors are available as slip-ring induction motors and squirrel-cage induction motors.
- The gear motors have numerous applications in the field of industrial machines over the low rpm induction motors.
Conclusion:
Thus, the reason for the usage of gear motors in many industrial machines instead of low rpm induction motors is explained.
