Bench tests
DYNAMOTOR STARTER MOTOR BOSCH TYPE AND EFEL TYPE
CARAT ELECTROMAGNETIC CHECK
1) No-load test: the starter motor, under no-load, must draw a maximum of 15 Amp. with a supply voltage
of 11.5 to 12V and must rotate at rpm 1'>=2500.
2) Load test: braking the starter motor so that it draws 120 Amp, and with a supply voltage of 9.2 to 9.4
V a torque >= 520 kgm must be obtained, for no lower than 1000 at 1'.
3) Pickup test: with rotor locked and a supply voltage 7.5 to 7.8V the current drawn must not be higher
than 260 Amp and the torque must be no lower than 1200 kgm.
KEY:
*= Starter button
**= Solenoid
***= Voltage regulator
****= Dynamotor
*****= 12V battery - 24 Ah
N.B.
THESE CHARACTERISTICS ARE TO BE OBSERVED ONCE YOU HAVE FOR TURNED THE DY-
NAMOTOR FOR 30" IN THE CONDITIONS DESCRIBED IN POINT 1).
