MOTORS FOR TRAM DRIVES

This paper presents an examination of different electric motors used in variable speed drives such as drives for roll mills, or drives that need to operate with minimum energy consumption. The drives can run on a dc motor with electromagnetic excitation from a power electronics converter, or one excited by permanent magnets. They can also run on a cage induction motor, a slip-ring induction motor or a brushless motor. The various options are considered, and a table is presented with parameter for five different specifications across the motor types. The brushless motor with an electronic commutator excited with permanent magnets has the best operational parameters, with the power and efficiency ratings the highest. It is as reliable as a cage induction motor since there are no movable contacts and no active power losses in the rotor. It also ensures the highest overload capacity of all the investigated motors.
