Feature: 1. Function: Testing device can quickly detect the quality of the controller, quickly test whether the brushless motor coils good or bad, quickly check the brake handle. 2. Features: Fast detection of phase sequence ABC and ABC color of brushless motor, quickly detect whether the phase angle is 60 degrees or 120 degrees. 3. Application: The testing device is a necessary tool for electric vehicle manufacturers, controller manufacturers, motor manufacturers, electric vehicle dealers, and electric vehicle after sales maintenance personnel. 4. Exquisite Workmanship: The electric bicycle tester is made by excellent workmanship, which can provide accurate detection and has good detection effect, with outstanding performance. 5. High Efficiency: Brushless motor controller is high efficiency, small size, light weight, easy to carry, convenient for you to use, and bring you a good use experience. Specification: Item Type: Brushless Motor Controller Tester .Material: ABSProduct Introduction: 1. The multi function maintenance tester for electric vehicles is applicable to the detection of 24V, 36V, 48V, 60V72V brushless controllers, brushless motor coils, inner hall and rotary handle of brushless motors, and the angle discrimination of brushless motors. 2. The portable multi function maintenance tester for electric vehicles is a simple portable testing instrument specially used to quickly test the quality of electric vehicle brushless controllers and brushless motors (including the quality of motor windings and for Hall), the phase angle of 60 degrees or 120 degrees.3. It is a necessary tool for electric vehicle manufacturers, controller manufacturers, motor manufacturers, electric vehicle dealers, and electric vehicle after-sales maintenance personnel. 4. The car repair kit only assists in the detection and diagnosis of faults. The detection controller does not fully detect the fault, but only detects the phase line and for Hall line interfaces of the controller. 5. If the rotary handle signal components and power off switch components in the controller are damaged, the controller will not work properly. The car repair kit cannot judge! Product Features: 1. Fast detection of brushless motor, for Hall phase sequence of motor and motor winding 2. Quickly detect the motor and controller phase angle of 60 degrees or 120 degrees 3. Quickly detect the quality of the controller 4. Fast wiring between brushless motor and controller 5. Quickly check the brake handle Scope of Application: 1. Fast detection of brushless controller 2. Fast detection of brushless motor coil 3. Fast detection of hall of brushless motor 4. Quickly detect whether the phase angle is 60 degrees or 120 degrees 5. Fast detection of phase sequence ABC and ABC color of brushless motor 6. Quickly detect the quality of speed regulating handle (accurate measurement) (The handle detection indicator light is green, then off, and then red, which is a good handle) 7. Quick check the brake handle Package List: 1 x Brushless Motor Controller Tester1 x User Manual
