DC motor: Center Height 100 - 355 is the People's Republic of China machinery industry standard JB/T6316-92 Z4 series DC motor technology "under the standard series of small DC motors; Centre 400 - 450mm for expansion beyond the standard series Z4 DC motor. Z4 series DC motors (center height 100 - 450mm) is our latest products, the series motors can be widely used in metallurgical industry mill, metal-cutting machine tools, paper, dyeing, printing, cement, plastics extrusion machinery and other class industrial sector, applicable to a wide range of speed, power overload capacity of not more than 1.6 times the drag. Constant rates of weak magnetic upward speed range can be achieved for different specifications of 1.0 - 3.0 times the rated speed, constant torque lower down the armature voltage governor lowest 20r/min Guozainengli see Appendix A. Z4 Series DC motor than the Z2, Z3 series has more advantages, it is unfair available the DC unit supply more applicable to stationary rectifier power supply. And the moment of inertia is small, has a good dynamic performance, and the rate of change with higher load, especially suitable for smooth adjustment, high efficiency, automatic steady speed, reaction recorded sensitive control system, with the current international advanced level. Motor fixed continuous continuous rating, no more than 1000m in altitude, ambient air temperature does not exceed 40 ° C in the region, the motor is run according to the data in the technical data sheet rated. This series motor is class F insulation. Z4 Series DC motor power range from 1.5KW to 600KW standard rated voltage of 160V and 440V. Rated speed 3000,1500,1000,750,600,500,400,200 r / min total of nine excitation mode is excited, the excitation voltage of 180V. In addition to the level of the above provisions, according to the specific circumstances and needs of users, can derive power armature voltage, speed and excitation voltage value. Rated voltage of 160V motor, in the case of single-phase bridge rectifier power supply, the general need the charged reactor, external inductance value of the reactor in the motor nameplate. Rated voltage of 440V motor, all without an external reactor. This series of motor performance not only conforms to GB GB/T755 "basic technical requirements for rotating electrical machines, also in line with the German VDE0530 standard.
