Z4 series dc motors are widely used as prime mover for various machinery, such as mill auxiliary in metallurgical industry, metal cutting machine-tool, paper making, print, textile, printing and dyeing, cement-making, plastic extruding machine, etc.

**Main features:
1. The performances & tehcnical details meet IEC34-1 or DIN57530.
2. The mounting dimensions conform with international standard IEC72, except for the dimension B - axial distance between the mounting holes.
3. Class F insulated, with reliable insulating construction and impregnating progress.
4. Angular body shape maximizes the space utilization.

**Advantage:
small size, light weight, good performance, light weight, large output, high efficiency, reliability.
Quality is being able to match the current international advaced level.

3. Field voltage is 180V or as required;
4. Cooling method:  Forced ventilating. IC06, IC17, IC37, IC86W are available;
5. Protection:  IP21S, IP23, IP44, IP54;
6. Mounting type: IMB3, IMB35, IMV1, IMV15.

**Working conditions:
1. Duty: continuous S1;
2. Ambient temperature: -15 ~ +40 Celsius degree;
3. Altitude: within 1000m;
4. The Ambinet conditions should be free from acidic, alkali fumes of other aggressice gases which corrode insulation;

** The choice of the motors capacity
1.First kind (A): Ordinary industrial DC motor. The technical data of this kind of motor please see the technical data table. The buyer can decide the capacity, voltage, running speed and the method of cooling of the motor at the buyers option.
2. Second kind (B): Metal rolling mill DC motor. The output power of this kind of motor is about 20% lower than kind (A), the detail numerical value can be negotiated by the user and the manufacture.
3. Exclude the specification of technical data in the table. Manufacturer can derive other specification at the requirement of the user.
