ZDD type conical rotor brake dual speed three-phase asynchronous motorDetailed product description：

The ZDD type conical rotor brake dual speed three-phase asynchronous motor has two speeds, fast and slow, and its characteristics can vary power and speed in stages according to different load requirements, thus achieving reasonable matching with the load. This is of great significance for simplifying the variable speed system and saving energy. Therefore, in addition to being matched with electric hoists, it is also widely used in transmission mechanisms such as lifting and transportation machinery, machine tools, and production lines that require two speeds and rapid braking. The rated voltage of this series of motors is 380V (50Hz). The benchmark working system is S3, with a load duration rate of 25% and a starting frequency of 120 times per hour when powered on. Our company's variable speed cone motor products come in several pole ratios such as 2/8, 2/12, 4/8, 4/12, 4/16, etc., with a complete range of power levels. Customers are welcome to contact us for ordering.

Structure Introduction:

The ZDD type conical rotor brake dual speed three-phase asynchronous motor is a horizontal motor that uses a conical surface brake. The output shaft extends as a rectangular spline, and the base does not have a foot. The front end cover has a flange (flange type), and the installation hole is on the flange of the front end cover. This series of motors is a closed structure with a protection level of IP44. The cooling method is self fan cooling IC0141, and the insulation level is B or F.
