First, Sima motor Z4 series DC motor overview
    Z4 series DC motor: The center height is 100-355mm, which is the standard series small DC motor 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 is 400-450mm except the standard series. Expansion of Z4 DC motor; center height of 500 ~ 710mm is a newly developed medium-sized DC motor. 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. Sima Motor official website:
    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. Sima Motor official website:
    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. Sima Motor Products:
   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.

   The performance of this series of motors not only meets the national standard GB/T755 "Basic Technical Requirements for Rotating Electric Machines", but also basically conforms to the German VDE0530 standard.
Model meaning: Z4-280-11B, Z means DC motor, 4 means 4 series, 280 means motor center height (mm), the first 1 means the core length serial number, the second 1 means the front end cover number, 1 is the short end Cover, 2 is the long end cover, B indicates the compensation winding.
Note: For the Z4-112/2-1 model, the first digit after “/” represents the pole number, and the second digit represents the core length number.
Second, Sima motor Z4 series DC motor structure
(1) Basic structure Sima high voltage motor:
The Z4 series DC motor adopts an octagonal full laminated structure, which not only has high space utilization, but also can withstand pulsating current and rapid load current change when powered by a static rectifier.
Z4 series DC motors generally do not have series excitation windings, which are suitable for automatic control technology that requires forward and reverse rotation. It can also be made with series excitation winding according to user needs. The motor with a center height of 100 to 280 mm has no compensation winding, but the motor with a center height of 250 mm and 280 mm can be made with a compensation winding according to the specific conditions and needs. The motor with a center height of 315 to 450 mm has a compensation winding.
The shape and technical requirements of the motor with a center height of 500-710mm are in line with the IEC international standard, and the mechanical dimensional tolerance of the motor conforms to the ISO international standard.
(2) Cooling method and structure, installation form
IC06: External ventilation with blower;
ICl7: the cooling air inlet is a pipe, and the outlet is a blind window exhausting;
IC37: that is, the cooling air inlet and outlet are pipelines;
IC611: fully enclosed air/air cooler; Sima high voltage motor:
ICW37A86: Fully enclosed air/water cooler.
And there are a variety of derivative forms, such as self-venting type, with axial fan type, closed type, air/air cooler type. See Table 1 for the cooling air volume, wind pressure, and fan motor power required for each frame motor. The basic protection level of the whole series of motors is IP21S.

The installation form of this series of motors complies with the provisions of GB/T997 "Motor Structure Installation Type and Code". The installation dimensions of the motor are in accordance with the IEC standard except for the axial distance of the foot hole (B size).
   The position of the motor outlet box is viewed from the drive end (non-commutator end) on the right side of the base (ie, the positive box). If the user requests the outlet box to be placed on the other side of the base, the reverse box is indicated when ordering. The basic output shaft of the motor is a single shaft extension, and the direction of the exit axis of the outlet box (the positive box) is the left exit shaft. Double shaft extension can also be made 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 motor is a flexible coupling, and it can also be used for a certain radial force transmission (belt or gear transmission). This article is reproduced from:
