When specifying rotation, also state if viewed from the shaft end or the opposite shaft end of the motor. The rotating component of an induction AC motor. It is typically constructed of a laminated, cylindrical iron core with slots of cast-aluminum conductors. A 1.10 SF motor should not be loaded beyond its rated horsepower. Service factors will vary for different horsepower motors and for different speeds.
Motor has low starting torque, low cost.
Usually used in direct-drive fans and small blowers, and in small gearmotors. Motor has moderate starting torque, high breakdown torque. The amount by which a motor, operating under rated conditions, is hotter than its surrounding ambient temperature. A device, sensitive to current and heat, which protects the motor against overheating due to overload or failure to start. Basic types include automatic rest, manual reset and resistance temperature detectors.
