General Descriptions:
Z900 DC motor is a products of Z series direct current motors that our company developed newly, The center height of electric machinery is 900mm, This type electric motor is an upgrading products, After our company's absorption of the advanced technologies both from domestic and aborad, Z900 DC motor is suitable for the motive power machine whose transmission speed need to be adjusted, Such as rolling mill, winch for mine, shipping, testing equipments. etc,
Working Conditions:
1, The excitation way of the motor is separate excitation, the excitation winding generally has four lead terminals, the voltage of excitation is 110 volts or 220volts
Electrical machinery allow excitation by force, and this voltage mustn't exceed 550 volts,
2. Up to 100times/second to the voltage rating is allowed in the electric current of main circuit of the motor(di/dt)
3. The motor circumrotates to one direction, the clockwise rotation is from the transmission hauling part, we can design it as bi-direction according to the user's requirement.
