3. Heat up the stator housing (55). If possible, use a furnace to ensure even heating.
WARNING
Hot surface
Death or serious personal
injury
‐ Do not touch the
heated parts surfaces.
Wear protective
clothing.
TM084261
T1
External surface temperature. Must not exceed 210 °C and must be maintained for a maximum of
15 minutes.
T2 Internal surface temperature. 210 °C during stator insertion.
4. After stator insertion, wait until the stator housing cools down to room temperature, then perform insulation resistance and sensor tests
according to the following:
Insulation resistance measurement points
Between stator phase leads and the stator housing
U1+U2+V1+V2+W1+W2 - Stator housing
Between stator phase leads and stator ground wire U1+U2+V1+V2+W1+W2 - PE
Insulation resistance test parameters
Duration:
60 seconds
Voltage: 1000 V
Voltage upper limit: 1020 V
Voltage lower limit: 980 V
Min. resistance: 1000 mΩ
Max. resistance: 20000 mΩ
Sensor and switch test
Thermal protectors (PTO) continuity test
Terminals: 2TB1-2TB2
Resistance: < 320 mΩ
