What are the torque capabilities of a split phase motor?

• A. High starting torque, high running torque
• B. Low starting torque, medium running torque
• C. No starting torque, low running torque
• D. Medium starting torque, low running torque

Answer: (B)

The capabilities of a split phase motor are characterized by its ability to provide low starting torque and medium running torque. This type of motor is designed to operate efficiently at normal load conditions but is not ideal for applications requiring a high starting torque. When the motor starts, it relies on the phase shift created by the auxiliary winding to generate enough torque. However, this initial torque is typically not sufficient for high-inertia loads, making it unsuitable for heavy starting applications. Once the motor reaches running speed, it operates with a moderate level of running torque that can handle typical loads more effectively. This balance makes split phase motors well-suited for applications such as fans, blowers, and small pumps, where high starting torque isn't a critical requirement, but consistent running performance is essential. The other options describe torque capabilities that do not accurately match the characteristics of split phase motors, focusing either on high starting torque, no starting torque, or a combination of higher running torque than is typical for this type of motor.
