elevator door machine motor ThyssenKrupp 125ST-13 Elevator Permanent magnet synchronous motor parts

There are three types of motors commonly used in the market, permanent magnet synchronous elevator door machines, AC door machines and DC door machines. In the past two years, permanent magnet synchronous motors will gradually replace the other two types of motors. Permanent magnet synchronous door machines have only been on the market for two years, but the current torque is in the range of 1.8~2.6Nm, which has limitations for large freight elevator doors and heavy doors. In particular, they cannot work for a long time in a high temperature environment. Generally, the torque should be 3.0~5.0Nm to cover elevator doors of 120Kg~320Kg.
