Patent

CA 2384258

A permanent magnet electric motor for elevator or lift installations, comprising a stator (7) and a rotor (1, 2). The rotor comprises at least two rings (1) with permanent magnets (2) fixed on their outer surfaces. Said rings (1) are mounted on a frame (3) and are laterally fastened together by fastening and alignment means (4) in order to obtain a rotor unity. The same or similar rings are employed for motors of different rotor lengths, defining stan- dard rotor lengths of multiple values of the rotor length. The rings (1) may be shifted with a suitable angle to permit the generation of a skewing effect of the magnets which reduces or eliminates a cogging torque of the motor. The rotor of said motor can be easily and quickly installed and/or removed in very small spaces, specially of elevator or lift installa- tions.
