What is the approximate starting current of a split phase or capacitor start motor?

The starting current of a split phase or capacitor start motor is typically about 5 to 6 times the normal running current. This high starting current is a characteristic of these types of motors, which need a significant amount of torque to overcome inertia and initiate movement. The design of split phase and capacitor start motors enables them to generate a stronger magnetic field at the start, allowing the motor to achieve the necessary torque effectively.

In contrast, other types of motors may have different starting current characteristics based on their construction and operation. The specific requirement for a high starting current underscores why it is crucial for professionals working with these motors to account for this demand when designing circuits and selecting protective devices, such as circuit breakers or fuses, to ensure proper operation without nuisance tripping during start-up. Understanding this aspect is essential for those involved in the maintenance and repair of commercial food equipment.
