Product introduction:
ZFQZ series DC motor is a series of products developed by our company on the basis of Z4 series DC motor and drawing on the main technology of ZZJ-800 series DC motor. The moment of inertia of the motor is 45% of that of ZZJ-800 series and ZZJ-900 series. and 65%, adapt to the harsh working conditions of frequent forward and reverse rotation and frequent starting and braking. The motor has excellent overload characteristics. Its maximum torque and starting torque are 112% and 117% times that of ZZJ-800 series and ZZJ-900 series respectively. The weight of the motor is only 65% ​​of that of the ZZJ-800 series. Comply with the international standard IEC34-13 "Technical Specifications for Auxiliary Motors for Lifting and Metallurgy". The external dimensions of the motor are in line with the IEC72 international standard except for the axial dimension "B" between the two foot holes. The motor can reach the main installation dimensions consistent with the ZZJ-800 and ZZJ-900 series through the base plate, and can be made through negotiation. The shaft extension size corresponding to ZZJ-800 and ZZJ-900 series can be replaced by ZZJ-800 and ZZJ-900 series products.

The cooling method and enclosure protection level of the motor are as follows:
Cooling method Single-pipe air inlet (IC17); double-pipe air inlet and outlet (IC37); with air-water cooler (IC86W)
Protection class: IP23S; IP44 ; IP44
2. Motor installation form: horizontal foot installation (1MB3). The motor can be manufactured with single-shaft extension or double-shaft extension, and the single-shaft extension motor can be equipped with a tachogenerator or other speed-measuring device on the non-transmission side.
3. If the user needs, the thermistor or other overheat protection components can be embedded in the stator winding of the motor.
4. The position of the outlet box is on the right side of the base from the transmission side, and can also be on the left or above the base if the user needs.
