Answer Posted / Amitesh Srivastava
The acceptable values for Tan Delta (power factor) and dissipation factor (loss factor) depend on the specific motor design, operating conditions, and application requirements. Typically, a power factor of 0.9 or higher is considered acceptable for electrical motors, while the dissipation factor should be as low as possible to minimize heat generation.
