9. STARTING MOTOR 9.1.8 Characteristic test Since the characteristics can be checked roughly by means of a simple no-load test as explained below. Note: Complete the test quickly since the rating of the starting motor is 30 seconds. (1) No-load test Fix the starting motor on a test bench and connect wiring as shown below. When the switch is closed, a cur- rent flows in the starting motor, which is rotated at no-load. Measure the current, voltage and number of revolutions then and check if they satisfy the specified characteristics. 82E-5 – 98E-5 SERIES 9-17
