Geared Lift Traction Machine Motors are generally preferred by buildings with machine room. Various speed options are available. Geared (MR) machines lift motors are usually preferred for the elevator motor structures in the engine room.
Gearless Lift Machine motors (MRL) are available with various speed options generally as a solution for the buildings without machine room. Gearless Machine Motors commonly known as MRL elevator machine motor developed as solutions in buildings without ma
Asynchronous Motors
A geared traction machine typically uses an asynchronous induction motor. The term “induction” refers to how the rotor magnetic field is generated. The sinusoidal AC current applied to a stator winding and the geometric placing of the three-phase stator windings creates a rotating magnetic field. As the magnetic field moves past the rotor bars, the magnetic flux is cut, and a voltage is induced unto the rotor bars. The induced current creates an opposing electromagnetic field on the rotor, which follows the stator. The interaction between these two fields results in mechanical torque, which, in turn, causes rotation of the rotor. Sintered Neodymium Motor Magnet N42H Epoxy Plating for DC Motor
However, for an induced voltage to be present, the magnetic flux lines across the rotor windings must be moving relative to them. If the rotor were to move at the same speed as the stator field, there would be no change in magnetic flux across the rotor bars, and therefore no induced voltage on the rotor and no induced field. The result is no torque production. So, the rotor must be moving at a speed asynchronous to the stator.
