General description:The Z series medium size DC motors are new products of the works developed with latest technology of design and manufacturing,there are six shaft height for motor frames ranging from 315-560mm.the performance,outline dimensions and technical specifications of the motors conform to the standard of our country(GB) and international electric committee(IEC),while the mechanic dimensions tolerance of the motors conform to the standard of international Standard Organization(ISO).
Working conditions:1, it is allowed to install this series 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 allklimaterial,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 be fore signing contracts;4, the motors can reach its rated power under the working condition of less than 1000m sea level height and 40 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.
Products performance:1, continuous working system(S1) is applied;2, the standard rated voltage of this series motors are 220V,380V,440V,550V and 660V,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 winging are divided into two groups are in series or parallel connection,the excitation voltage is 220V or 110V respectively,excitation voltage beyond the scope can be negotiated;
