Specification: The Ziehl-Abegg ZETATOP SM250 offers an innovative traction sheave motor for cantilever elevators. The ZETATOP meets all requirements for this kind of motor: A machine-room is not necessary, the motor is mounted directly in the shaft head. As a result of the extremely high torque of the ZETATOP motor, the suspension of the elevator can be 1:1. No diverting pulleys are necessary, therefore the construction is simple and cost effective.
Attributes and special features: The ZETATOP offers all of the advantages of a modern permanent magnet excited synchronous motor. It is compact and can be mounted in many ways, even in the smallest elevator shaft. The ride quality and the smoothness of these kinds of drives is unsurpassed. The certified brake can be used in addition as a safety device against uncontrolled car movement upwards.
