ZD1 conical rotor brake three-phase asynchronous motor, ZD series conical rotor brake three-phase asynchronous motor conical rotor brake asynchronous motor is divided into lifting motor and running motor, mainly for electric hoist (CD type and MD type) supporting motor, ZD series motor with automatic brake device, with the characteristics of large starting torque, reliable braking, compact structure, stable operation, small size, light weight, safe use, easy maintenance, etc.
Specifications of main lifting motor of electric hoist:
The ZD1 conical rotor brake three-phase asynchronous motor adopts a conical brake, the output shaft extension is a rectangular spline, the machine base does not have a foot, the front cover has a flange (flange type), and the mounting hole is on the front cover flange. This series of motors is a closed structure, the protection level is IP44, the cooling method is self-fan cooling IC0141, and the insulation level is Class B. Scope of application ZD series motors are commonly used in the lifting machinery industry, the lifting motor of electric hoists, or for drive devices that require large starting torque and large braking torque. They can also be used in machine tools, production lines and other occasions that require rapid braking, special mechanical equipment requires rapid braking, frequent starting, and alternating forward and reverse operation. It is not suitable for working environments with flammable and explosive materials, molten metals, explosion hazards, and acid and alkali steam.
