Electric vehicle multifunctional maintenance tester is suitable for 24V, 36V, 48V, 60V 72V brushless controller, brushless motor coil, brushless motor inner hall, handle detection and brushless motor angle distinction. Portable electric vehicle multifunctional maintenance tester is specially used to quickly detect the quality of the brushless controller and brushless motor of the electric vehicle (including the quality of the motor winding and the Hall). The phase angle is 60 degrees or 120 degrees. A simple and portable testing instrument is an indispensable tool for electric vehicle manufacturers, controller manufacturers, motor manufacturers, electric vehicle dealers, and electric vehicle after-sales maintenance personnel. As long as it is 5 Hall fine wires, 3 thick main phase wires and 8 wires in total, the brushless motor can be detected, and the gearless is the stepless speed change. For example, the greater the rotation of the electric vehicle handlebar, the higher the motor speed. Dual-mode Hallless controller cannot detect The differential motor is a high-speed motor. When testing, turn the wheel (motor) faster, so the test will be better and more obvious. colour:white Material:metal Package Contents: 1*Electric Car E-bike Scooter Brushless Motor Controller Tester Only the above package content, other products are not included.
