Z4 Series DC Motor-Z4-225-31 132KW DC Motor Product Brief:

The center height of 100-355mm is the standard series of small DC motors specified by the mechanical industry standard JB/T6316-92 "Z4 series DC motor technical conditions" of the People's Republic of China; the center height 400-450mm is the extended Z4 DC motor outside the standard series; The center height of 500 ~ 710mm is a medium-sized DC motor newly developed by our factory. This series of motors can be widely used in metallurgical industry rolling mills, metal cutting machine tools, paper making, dyeing and weaving, printing, cement, plastic extrusion machinery and other industrial sectors. The Z4 series DC motor has greater advantages than the Z2 and Z3 series. It can be powered not only by the DC unit power supply, but also for the static rectification power supply. Moreover, the moment of inertia is small, has good dynamic performance, and can withstand high load change rate, and is especially suitable for a control system that requires smooth speed regulation, high efficiency, automatic steady speed, and responsiveness, and has the international advanced level. The rating of the motor is continuous continuous rating. In areas where the altitude does not exceed 1000 m and the ambient air temperature does not exceed 40 °C, the motor can be rated for operation according to the data in the technical data sheet. This series of motors uses Class F insulation. The power range of Z4 series DC motors ranges from 1.5kW to 840kW. There are nine kinds of rated speeds of 3000, 1500, 1000, 750, 600, 500, 400, 300, 200r/min. The excitation mode is separately excited and the excitation voltage is 180V. In addition to the above specified levels, other power, armature voltage, speed and excitation voltage values can be derived depending on the specific situation and the needs of the user. A motor with a rated voltage of 160V is usually operated with a reactor in the case of a single-phase bridge rectifier. The inductance of the external reactor is indicated on the motor nameplate. Motors with a rated voltage of 440V do not require an external reactor.
