Basic Information

The series dc motors' feature: 1.carbon brush easily replaced 3.efficient and long continuous running time 4. double shaft and with a foot to be convenient for the customers' need. 5. Six teeth male spline Use and Maintenance Manual for ZC series of DC Traction Motor A.The motor is applicable to various electric vehicles with storage battery powered, such as electric motor, forklift, loader, stacking truck, motorcycle and other electric motors used for walking. 1. Application environment: a: Altitude is not more than 1200 M. b: The ambient temperature is no more than 40 °C, and the minimum is no less than -25 °C. c: The relative humidity is up to 100%, and condensation forms on the surface of the motor. 2. To meet many operation conditions under which vehicles start with overload, climb with full load and run at high speed on flat roads, all will be achieved not relying on mechanical speed regulation.B.Structure of Motor1. The motor is a series excited DC motor, mainly comprising a stator, rotor, brush cover and drive cover and other components. 2. The motor is divided into the fully open and closed types and others. The fully closed type can prevent foreign body, dust and water and other substances from entering, and the commutator and electric brush of the open type can be more easily maintained and replaced. 3. The wire and commutator of the armature are welded by TIG, and are connected reliably and can be applicable to various harsh working environments. 4. See the appearance diagram or the requirements of the order form for the specific appearance and technical parameters C.Use and Maintenance of Motor: 1. Uses in accordance with the requirements of the specification can ensure the normal operation of the motor. 2. The motor should be kept in ventilation, dry and clean places; if the preservation time is too long (six months), the grease of the motor should be checked, and its cold insulation resistance should be measured and the resistance value should be not less than 0.5 M Ω, if not, the motor must be placed in an oven at the temperature of 80 °C ± 10 °C for drying. 3. Prior to installation, inspect and confirm whether there are bearings at the extension end of the motor shaft (the extension end of the shaft can be manually light swayed, and the motor has no bearings if the extension end of the shaft can be swayed); if the extension end of motor shaft has no bearings, it is necessary to ensure that the coaxial degree of the motor axis and the spigot outside the motor cover (spigot of the block) should be not more than 0.1 mm. After installation, inspect whether the armature can rotate flexibly, without wiping or collision phenomenon. 4. Check whether the motor connection is reliable. 5. Check whether there is dirt on the commutator surface and the electric brush slides freely in the brush box. 6. Under the idle load state, the motor (Series excited) cannot be allowed to be powered and operate. If users must operate it in the idle load state, the terminal voltage must be controlled at less than 15% of the rated voltage. 7. Cooling air should not contain corrosive gases. 8. When the environmental temperature is 40 °C, the allowed temperature rise for all components of the motor is shown in the following table: Part NameInsulation levelMeasurement methodAllowed temperaturerise (K)Armature windingsF/BResistance100/80Stator windingsResistance100/80CommutatorPoint temperature90/809. Check regularly whether the internal components of the motor are deformed and check the surface conditions of the commutator and the wear situation of the electric brush, if unusual, the motor will work again only after timely maintenance. The motor should be checked at least once in per half a year (the inspection cycle should be correspondingly reduced if the operation conditions of the electric vehicles are frequent and complicated) under the following methods: a: Removing dirt, fouling or carbon of the motor, to ensure the normal work of the motor. b: Cleaning or replacing the bearings, adding # 3 lithium grease into the roller after being cleaned. c: According to the wear situation of the electric brush, it will be replaced in a timely manner at a professional maintenance unit, and the wear-in arc surface of a new electric brush should be guaranteed to be not less than 70% before being put into operation.10. The maximum allowable current at a short-term overload of the motor is three times of the nominal value. Torque at overload at the time is 4.5 times of the nominal torque, and the time should not be more than one minute.11. The motor is under one hour work system and is not allowed to work overtime.12. The planned maintenance work should not be too few and should be done at least once a year.13. The documents with the motor: Certificate: A copy Product Manual: A copy14. The other accessories will be priced based on requirements of users in the additional article of the contract: Such as: electric brush for backup, lead wire of the motor and electric control.D. Warranty Period The complete motor has one-year warranty period (excluding the electric brush). Customer should use and maintain the motor in strict accordance with the fourth requirements above, and the motor fault caused by improper operations of users will not be within the scope of the warranty. During the warranty period, users should promptly contact the manufacturer if the motor is abnormal; and the manufacturer will not be responsible if the customers themselves treat the fault. Regarding overseas customer, because not the convenient post-sale service, may consult according to increases 3/1000 delivers goods, namely the customer volume of order achieves 1000 every time, Our company free bestows three motors.
