Z710-2B DC motor for High Speed Wire Rod Hot Rolling Finishing Mill
The Z710 DC motor has a center height of 770 mm.
Conditions of Use
1. The motor can be installed in harsh environmental conditions, but the correct cooling method and degree of protection must be chosen to keep the inside of the motor clean.
2. The cooling air required for electricity shall not contain gases such as acid or alkali which may damage the insulation and commutation performance of the motor.
3. Motors used in ships and wet tropical areas and in working environments with salt spray, moisture, etc., should be agreed separately.
4. The rated power of the motor is such that the altitude does not exceed 1000 meters and the ambient air temperature does not exceed 40c.
5. The power supply of the motor is a static rectification power supply, and a DC generator power supply can also be used.
Model Description
Structural features
The base of the motor adopts a polygonal laminated structure, which has the advantages of small volume, light weight, and the like, and is suitable for a thyristor rectifying power supply. The motor has an insulation rating of Class F. The motor adopts solventless paint vacuum pressure impregnation treatment (VP) to make the winding insulation have good moisture resistance, mechanical strength and excellent thermal conductivity. The armature core is assembled by silicon steel sheets and has good magnetic permeability. Rolling bearing, stable operation. The installation type of this motor complies with GB997 and IEC34-7 "Motor structure and installation form code".
Product performance
1. The rating of this motor is continuous operation mode (SI).
2. The standard rated voltage of this motor is 440V, 660V, 750V.
3. The excitation mode of the motor is separately excited. The excitation winding has four lead terminals, which are divided into two groups. The excitation voltage is 220V when connected in series, and the excitation voltage is 110V when connected in parallel. The actual excitation voltage of the motor should be based on the actual excitation current of the motor reaching the rated value. The motor is forcibly excited and the excitation voltage must not exceed 500V. When the excitation is strong, the excitation current can slightly exceed the rated excitation current, but the excitation current must not exceed after the excitation current is stable.
The 710-2B DC motor can withstand the short-term (one-minute) overload specified in the table below:
| Percentage of base speed | Percentage of rated current | |
| Occasionally used | Frequently used | |
| 100 200 More than 300 | 200 200 175 | 175 160 140 |
