Z Series Dc Motor

1. Continuous working system (S1) is applied.
2. The standard rated voltage of this series motors are 220V, 330V, 440V, 550V, 660V and 750V. The voltage beyond above scope can be negotiated when placing orders.
3. Separate excitation is the basic excitation type of this series motors. Four terminals of the excitation winding are divided into two groups. In case the two groups are in series or parallel connection, the excitation voltage is 220V or ll0V respectively. Excitation voltage
beyond the scope can be negotiated.Forced excitation is allowed with the voltage of less than 500V.During forced excitation,the transient excitation current can exceed the rated excitation, current slightly until the excitation current gets stablilized.
4. Short time overload capability.

Products performance

1. It is allowed to install this seris motors in the environment with worse working conditions. However proper cooling and protection type should be chosen to keep the cleaness of the motors.
2.The cooling air should not contain acid or alkli material, which is harmful to the insulation and commutating pertormance of the motors.
3.In case the motors will be applied to marines, tropical and humid areas, or the areas with salt and humid air, please notify before signing contracts.
4.The motors can reach its tated power under the working condition of less than 1000m sea level height and 40E ambient temperature.
5.The power source for the motors can be provided by static rectified source or DC generator.
6.In case the motor is powered by static rectified source, the number of pluse wave should not be less than 6,the peak ripple wave factor not be over 10% under the rated speed, voltage and load current.

Working conditions

The Z series medium size DC motors are new products of the works developed with latest technology of design and manufacturing.There are eight shaft heights for motor frames ranging from 315-710mm.The performance, outline dimenaions and technical specifications of the motors conform to the standard of our coumtry(GB)and lnternational Electric Committee(IEC), while the mechanic dimensions tolerance of the motors conform to the standard of International Stadard Organization(ISO).
