YZTDE Electromagnetic brake multi speed three-phase asynchronous motorDetailed product description：

The electromagnetic brake multi speed three-phase asynchronous motor used in the YZTDE series tower crane is made by adding an electromagnetic power-off brake to the non shaft extension end of the multi speed three-phase asynchronous motor used in the YZTD series tower crane. The motor and brake are coaxially connected, and using the same master control device can achieve accurate synchronization of starting and braking. Therefore, it is particularly suitable for tower crane lifting and amplitude changing mechanisms that require slow starting, accurate positioning, and reciprocating operation.

The motor adopts a single armature design, with small size, light weight, and beautiful appearance. The installation structure of the motor is divided into two types: IMB3 and IMB5. For high-power motors, B3 is generally designed and suitable for tower crane lifting mechanisms; Low power B5 design, suitable for tower crane amplitude mechanism. There are two types of motors: three speed and two speed. The reference working system for a three speed motor is S3-40% for high and medium speeds, and S3-25% for low speeds; The high speed of the dual speed motor is S3-40%, and the low speed is S3-25%. The motor has F-class insulation and protection level IP44; Cooling method IC411; Rated voltage 380V; rated frequency 50Hz.

The YZTDE series tower crane uses electromagnetic braking multi speed three-phase asynchronous motors. The main products include YZTDE160M-4/8/20, YZTDE160M-4/8/16, YZTDE132S-4/8/16, YZTDE132S-2/4/16 and other small three speed motors. The motor adopts a high speed ratio design, and the amplitude mechanism can start and stop at low speed, and reciprocate at medium and high speed. It can achieve accurate positioning of starting and braking, as well as high and medium speed reciprocating operation. It is an ideal matching power for the amplitude mechanism of large and medium-sized tower cranes.
