A motor with a starting torque of 150% is typically designed for which application?

A motor with a starting torque of 150% is particularly suited for compressor applications due to the high initial resistance that compressors typically present when starting. Compressors often require a significant amount of torque to overcome the inertia and pressure within the system at startup, which leads to a higher demand for starting torque compared to other applications. This additional torque ensures that the compressor can start efficiently and maintain its operation without stalling or causing electrical issues.

In contrast, fan and pump applications generally require lower starting torques because they do not encounter the same level of resistance upon starting. Fans usually deal with air, which has minimal resistance compared to a pressurized gas or liquid, while pumps may also involve lower starting challenges depending on their construction and the fluid being moved. Conveyor systems, while potentially requiring a good amount of torque, typically do not reach the same level of initial resistance as compressors do. Therefore, the design of a motor with 150% starting torque aligns with the demanding nature of compressor operation.
