The ZFQZ series DC motor is a series of products developed by our company based on the Z4 series DC motor and drawing on the main technology of the ZZJ-800 series DC motor. The rotational inertia of the motor is 45% and 65% of the ZZJ-800 series and ZZJ-900 series, respectively, and it is suitable for harsh working conditions such as frequent forward and reverse rotation and frequent braking. The motor has excellent overload characteristics, with a maximum torque and starting torque that are 112% and 117% times that of the ZZJ-800 series and ZZJ-900 series, respectively. The motor weight is only 65% of that of the ZZJ-800 series, and the motor power level complies with the international standard IEC34-13 "Technical Specification for Auxiliary Motors for Lifting and Metallurgical Applications". The external dimensions of the motor, except for the axial dimension "B" between the two foot holes, comply with the IEC72 international standard. The motor can achieve the main installation dimensions consistent with the ZZJ-800 and ZZJ-900 series through the use of a base plate, and the corresponding shaft extension dimensions of the ZZJ-800 and ZZJ-900 series can be made through negotiation, thus replacing the ZZJ-800 and ZZJ-900 series products.

1. The cooling method and shell protection level of the motor are shown in the following table:

Cooling method: Single tube air inlet (IC17), dual tube air inlet and outlet (IC37), with air-water cooler (IC86W)

Protection level IP23S IP44 IP44

2. Motor installation form: horizontal foot installation (1MB3). Motors can be manufactured as single axis extension or double axis extension, and single axis extension motors can be equipped with speed generators or other speed measurement devices on the non transmission side.

3. If required by the user, thermistors or other overheat protection components can be embedded in the stator winding of the motor.

4. The outlet box is located on the right side of the machine base when viewed from the transmission side. If the user needs it, it can also be located on the left or above the machine base.

Before placing an order, please refer to the product sample to determine the required product model, specifications, and other data, and try to choose the standard specifications listed in the sample. Please specify the model, power, voltage, rotational speed, excitation method, excitation voltage, and structural installation form of the electric motor in the order contract
