MOT14540
The Trane MOT14540 is a high output 3 phase electric motor intended for use in Trane HVAC equipment applications. Despite the fact that one of the variants was listed as 402.4 x 177.8 inches, which most likely are the dimensions of the shipping crate. This one has 1.27 horsepower and its working speed is 840 RPM, so it can easily drive large fans, big compressors or other similar stuff. Thermal overload protection with automatic reset helps to protect the motor from overheating and to provide long service. The Trane MOT14540 is powered by a 480V, 3 phase electrical supply and uses ball bearings for efficient operation at 60 Hz.
