1) No-load test: the starter motor, when unloaded,
must absorb no more than 10A with a supply volt-
age
≥
12V and must rotate at
≥
15,000 rpm.
2) Load test: when the starter motor is so braked
that it absorbs 47A with supply voltage
≥
10V, tor-
que of
≥
0.2 N•m must be obtained at 10,000 rpm.
3) Static torque test: when the rotor is locked and
the supply voltage is <7V, the absorbed current
must not exceed 130A and the torque must be at
least 0.55 N•m
