Z4 series DC motors: The center height of 100 ～ 355mm is a standard series of small DC motors specified by the machinery industry standard of the People's Republic of China JB / T6316-92 "Technical Conditions of Z4 Series DC Motors"; the center height of 400 ~ 450mm is outside the standard series Expansion of the Z4 DC motor; the center height of 500-710mm is a new medium-sized DC motor developed by our factory. This series of Xima motors can be widely used in metallurgical industry rolling mills, metal cutting machine tools, papermaking, dyeing and weaving, printing, cement, plastic extrusion machinery and other industrial sectors.
Z4 series DC motors have greater advantages than Z2 and Z3 series. It can not only be powered by DC unit power, but also more suitable for stationary rectifier power supply. Moreover, the moment of inertia is small, it has good dynamic performance, and can withstand a high load change rate. It is especially suitable for control systems that require smooth speed regulation, high efficiency, automatic stable speed, and responsiveness, and has the international advanced level today.
The rating of the motor is a continuous rating for continuous work. In areas where the altitude does not exceed 1000m 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 Xima motors use F-class insulation.
The power range of Xi'an Xima Z4 series DC motors is from 1.5kW to 840kW, and there are nine kinds of rated speeds of 3000, 1500, 1000, 750, 600, 500, 400, 300, 200r / min. It is 180V. In addition to the above-specified levels, other power, armature voltage, rotation speed, and excitation voltage values can be derived according to specific conditions and user needs.
For a motor with a rated voltage of 160V, in the case of single-phase bridge rectifier power supply, it is generally necessary to work with a reactor. The inductance value of the external reactor is indicated on the motor nameplate. Motors with a rated voltage of 440V do not require external reactors.
The performance of this series of motors not only meets the national standard GB / T755 "Basic Technical Requirements for Rotating Motors", but also basically meets the German VDE0530 standard.
(1) Basic structure
Z4 series DC motor adopts octagonal full lamination structure, which not only has high space utilization rate, but also can withstand pulsating current and fast load current change when it is powered by static rectifier.
Z4 series DC motors generally do not have series excitation windings, and are suitable for automatic control technology that requires forward and reverse rotation. Can also be made with series excitation winding according to user needs. Motors with a center height of 100 to 280 mm have no compensation windings, but motors with a center height of 250 mm and 280 mm can be made with compensation windings according to specific conditions and needs. Motors with a center height of 315 to 450 mm have compensation windings.
The overall installation dimensions and technical requirements of the motor with a center height of 500 to 710mm are in accordance with IEC international standards, and the mechanical dimension tolerances of the motors are in accordance with ISO international standards.
(2) Cooling method, structure and installation form
IC06: External ventilation with blower;
ICl7: The cooling air inlet is a pipe, and the outlet is a louver exhaust;
IC37: The inlet and outlet of cooling air are all pipes;
IC611: Fully enclosed with air / air cooler;
ICW37A86: Fully enclosed with air / water cooler.
And there are many derived forms, such as self-ventilated, with axial fan type, closed type, air / air cooler type. The cooling air volume, wind pressure, and fan motor power required for each frame size motor are shown in Table 1. The basic protection grade of the entire series of motor enclosures is IP21S.
|cabin seat no||Air volume (m3 / h)||Static pressure (Pa)||Fan motor|
|Power (kW)||Frequency (Hz)||Three-phase voltage (V)|
|Z4-112 / 2||220||300||0.06|
|Z4-112 / 4-1||220||300||0.06|
|Z4-112 / 4-2||360||450||0.18|
The installation form of this series of Xima motors complies with the requirements of GB / T997 "Motor Structure Installation Types and Codes". Except for the axial distance of the foot hole (B dimension), the other dimensions meet the IEC standards.
The position of the motor outlet box is viewed from the transmission end (not the commutator end) on the right side of the frame (that is, the positive box). If the user requires the outlet box to be placed on the other side of the frame, specify the reverse box when ordering. The basic output shaft of the motor is uniaxial extension, and the output shaft direction facing the outlet box (positive box) is the left outlet shaft. It can also be made into biaxial extension if required by the user. The basic direction of rotation of the shaft is viewed counterclockwise from the end of the commutator. The transmission mode of the electric motor is an elastic coupling connection, and it can also be used for a certain radial force transmission mode (belt or gear transmission).
Accessories for electric motors
According to the user's needs, the motor can be designed into a structural form that can be equipped with a speed measuring generator, pulse generator, centrifugal switch and brake, etc. The specific requirements can be negotiated with our factory.
Note: The specifications, power, and field weakening speed adjustment range in the technical data table are for reference only. In order to continuously adopt new technologies and new materials, the data in the table may change.
