Technical requirement


1. All parts should be kept clean and intact before assembly; when installing the motor to tighten the threads, add thread locking and sealant, and tighten the torque in accordance with
the standards. Tighten crosswise, symmetrically, gradually and evenly, and the threads must be marked after tightening; during the assembly process, the stator and rotor air gaps
should be ensured to be uniform, without friction and abnormal noise, and no foreign matter should enter the inside of the motor; after assembly, the overall appearance of the
product is clean and free of dirt , no obvious defects, all labels are firmly in the correct position; turn it gently by hand, the motor should be light and free of jamming.
2. Facing the motor output shaft, when the letter sequence of the motor wire ends is the same as the power phase sequence, the motor rotation direction is clockwise.
3. Coat the outer surface of the motor shaft extension with anti-rust oil for anti-rust treatment.
4. When installing the oil seal, check whether the lip is damaged or deformed, whether the spring is falling off or rusty, and apply an appropriate amount of lubricating oil between the lips of
the oil seal and the outer surface of the shaft extension; when installing, it must be installed flat and not tilted. For specific operations, refer to the "Skeleton Oil Seal Installation Process Code".
5. Dimensional tolerances not noted shall be based on GB/T1804-m level, and geometric tolerances shall be based on GB/T1184-k level;

7. Temperature sensor model: KTY84-150, resistance value at 20℃: 5442-6182.
The drive motor winding should be able to withstand the power frequency withstand voltage test of 1500VAC for the temperature sensor, the test time is lmin, and there should be no breakdown.
Leakage current is not greater than 5mA.
8. The water inlet and outlet of the motor are covered with rubber caps (manufacturer: Senrui Rubber, rubber cap number: 057831) to prevent dust when leaving the factory.
9. Safety test:
Definition of insulation resistance and withstand voltage of phase line pair chassis: cold insulation resistance is not less than 20M2 (DC1000V); withstand voltage is
1500VAC, 50Hz, 1min, and leakage current is not more than 10mA.

or flicker for 1-3s.
10. During debugging, it should operate flexibly, without stagnation or abnormal noise. During transportation, care should be taken to prevent collision and deformation.
11. There is no gap in the crimping of the speed sensor and temperature sensor connector pins at the wire inlet, there is no looseness in the wire compression part, and the
terminal pull-out force complies with QC/T 29106-2016 "Technical Conditions for Automobile Low-Voltage Wiring Harnesses" 4.4.6 Regulations, tensile test ≥110N;
12. The motor must meet the following standards:
GB/T 18488.1-2015 "Motors and Controllers for Electric Vehicles Part 1: Technical Conditions";
GB/T 18488.2-2015 "Motors and their controllers for electric vehicles - Part 2: Test methods";
GB/T 29307-2012 "Reliability test method of drive motor system for electric vehicles";
Environmental protection requirements comply with GB/T 30512-2014 "Requirements for Prohibited Substances in Automobiles".
