Automatically measures and records: Reversing load test sequence for DC Wiper & Reversible Wiper motors at incremental torque loads. Optional for fast testing via inertial dynamometer testing.
Provides static and dynamic performance tests( Torque, speed, Friction, Friction Spectrum, Spectrum of Torque& Speed Oscillation).
Provides valuable measurements unique to M.E.A technology (Parking position, Angle control and more…).
Tests One-Speed and Two-Speed DC Reversible Wiper Motor.
– Reversing load test sequence at incremental torque loads.
– Continuous mode test sequence at user predefined torque and time values.
– Providing Rated Torque/Speed/Current/Temp. vs. Angle/Time for CW and CCW rotations.
Rated torque/Speed/Current/Temperature vs. Angle/time, for CW and CCW. An example of a test report showing the results of a wiper motor at 3.25 Nm for 90 sec. is shown below in Figure 2. The system generates also an Excel report with all the source data. The negative torque values are for CCW direction.
After connecting the controller and the MUT (Wiper Motor Under Test) to the test bench, the system will supply the predefined voltage to the MUT. The loading unit will start loading the MUT in small torque incremental steps, from 0 Nm up to motor stall or to user “Predefined maximum torque”. The duration of each torque step extends for one CW/ CCW wipe cycle.
• Reversible wiper motor Speed/Current/Angle vs. Torque curves. • Speed/Current/Torque/Temperature vs. Time curves for the complete testing procedure. (*) Temperature measurements are given as optiona
For performance measurements in continuous mode, the user sets the predefined torque value and testing time. The system tests the motor at the user-predefined torque and time.
The system includes different testing procedures and capabilities for testing DC Reversible Wiper Motors.
