Split Phase Induction Motor Operation and CharacteristicsPreventing condensation in 3 phase AC motors Electrical

The starting torque is 150 to 200 per cent of the full load torque with a starting current of 6 to 8 times the full load current Due to their low cost split phase induction motors are most popular single phase motors in the marketFor 3 phase AC motors operating in damp conditions the best way to prevent condensation is to install resistance heaters inside the motor The installation of flexible resistance heating strips or coils is by far the simplest and least expensive method For example a heater and its installation in a typical 60 hp 364T frame motor will cost approximately $210 These strip space heaters
