Wiper motors are Low Torque, Low Speed DC motors mainly used in automobiles for window wiper applications under dual speed operation. Test rig designed to conduct a series of Performance and Endurance tests on these motors mainly consists of a suitably rated magnetic particle loading device for adjustable loading along with suitable sensors, special fixtures for clamping of different types of Wiper Motors, safety guards and interlocks. Wiper Motor test dynamometer are offered with proprietary software developed for motor test to monitor & display Input Power – Input Voltage, Motor current & Mechanical Output Power – Speed, Torque with Motor Efficiency, Temperature, Bearing Temperature, Winding Temperature etc. Two types of Controls are offered for Wiper Motor Testing, as: • Manual Controller - consisting Set Torque Potentiometer, Digital Torque Indicator, Digital Speed Indicator., Digital Indicators for Motor Input Voltage & Motor Current, Digital Power Indicator to indicate Watts / HP. • Motor Test Dynamometers are offered with PC based control panel with our proprietary APPSYS Motor Test software with Power analyzer. Test Reports having Torque-Speed characteristics, Torque-Current/Voltage and Speed-Current/Voltage, Efficiency characteristics, Torque-Speed Oscillations at steady state Torque at different temperatures, Temp measurements etc & custom characteristics required by clients, are exported & saved in MS Excel Tabular form& Graphs Accessories such as Motor Temperature, Winding Temperature measurements, Motors mounting Test bed, Test Stands with T slot having X, Y & Z adjustment for Length, Width & Height adjustments is also offered along with dynamometer. Following Tests are conducted on Wiper Motors: No load test: Test motor is run under no-load conditions for a preset time to record speed, voltage and current. Load test: Test motor is run under pre-settable torque/time settings. Under both low and high speeds to indicate and record performance parameters, when operated under various supply voltage conditions. Transient Dynamic Load Test: The motor is gradually loaded up from non-load to its full load limit in a controlled ramp and to lock condition with recording of the performance parameters. Stall Test: The motor is stalled for a predefined period with the recording of critical parameters at the end of the stall test. Differential speed test: The motor is switched ON with a specific supply voltage in low & hing speed modes and the differential speed is indicated. Minimum Start Voltage: An adjustable DC supply voltage is regulated remotely to note and record the minimum voltage at which the motor starts on no load condition. Auto Position Slip: An adjustable DC supply voltage is regulated remotely to evaluate the motor voltage at which the wiper arm tends to over travel.
