Machine room less elevators do not have a fixed machine room on the top of the hoistway, instead the traction hoisting machine is installed either on the top side wall of the hoistway or on the bottom of the hoistway. The motor is installed using a permanent magnet which “sticks” the motor permanently and work with Variable Voltage Variable Frequency (VVVF) drive. Some of the hosting machines are using gearless synchronous motors instead conventional induction motors. This design eleminates the need of a fixed machine room and thus saves much building`s space. Almost all the traction MRL elevators are gearless traction.
