Description

Series Z2 DC machine is used for industry. It’s suitable for electric power drag which timing range of constant power is not more than 1:2, over-loading capacity is not more than 1.5 rated torque. It also can be used for metal cutting machine tool, paper making, print, textile, cement-making, etc. Generator can be used for motive supply, illumination or other constant voltage supply. Booster generator is also suitable for charge and floating charge of large storage battery. 
In ordero adapt to adjusting voltage & speed in wide range when constant torque and accurate speed control, Z2 series has developed derive structure of strong wind and it’s detector, which electrical specification is wholly the same with Z2. But when Z2machine is equipped with ride style fan or double fan and speed indicating generator, it has compact structure and can run at a low speed for a long time, to make the use of wide range of adjustable-speed, accurate speed control. To meet the requirement of timing when constant torque, Z2 series electrical machine can be made to independent excitating generator with all kinds of excitating voltage to easily speed adjustment. According to different excitating power source, excitating voltage can be **0V, **0V, also can be other suitable voltage.
Furthermore, Z2 series can be adapted to other special demand, and in order to meet other special requirements. Z2 series derive some other specification:
1. ZT2 wide range of adjustable-speed motor: the range of adjust magnetism and speed when the motor is running at the constant power is 1:3 and 1:4. It is convenient for power supplying to constant voltage network which needs wide range of speed adjustment. To reduce the draught loss when running at a high speed, ZT2 which frame size is more than 7 commonlly adapt strong ventaging.
2.ZT2 special voltage motor: motor which rated voltage is **0V, **0V and **0V are suitable for *-phase and *-phase controlled silicon electrical source supply, motor which rated voltage is **5V and **0V can be use for mine traction drive power source and other situation which need special voltage & power source.
3.ZO2 enclosed type motor: fully-enclosed, suitable for special, dustproof working environment.
4.According to special needs, Z2 series can also derive with compensate winding motor and generator. At this time, the overload times can be increased to about 2.5 times of rated torque, and the time of constant armature loop can be reduced, it’s suitable for the situation which is large power servosystem or needs large overload torque. Presently, No.***1 frame have a part of specifications, if needed, can be developed. Above mentioned four kinds of special specifications, the overall dimension, moment of inertia and weight are same as Z2.
