Figure 20. Mechanical mounting connections of the electric machine (vertical mounting)
1 N-end ange (SAE 4 ywheel housing) with 12x30°xM10x1,5 bores. Depth of the thread is 19 mm.
Minimum bolt thread engagement of 16 mm is required.
2 Bores for the lifting eyes, N-end.
3 Shaft of the electric machine; spline structure of the shaft (DIN5480W50x2x24x8f)
4 D-end ange (SAE3). Use mounting bolts (12 pcs of DIN912 M10). Not included in the delivery.
Cooling connections
Make sure that cooling liquid runs freely into and out from the machine.
Connect the electric machine properly to the cooling circuit. Ensure that the coolant ow is equal
or higher than rated and the coolant temperature at the inlet of the machine cooling is lower or
equal to the rated temperature. For more information, see Chapter
Recommended coolants
and
product data sheet. Rated values can be found in the electric machine rating plate.
To connect the machine to cooling circuit, use connectors or adapter kit that can be attached to
G1/2 bores (2xM16x1,5).
It is recommended to use coolant connector equipped with o-ring seal or to use sealing washer
(for example Usit or Bonded seals) in the connection. In addition, it is recommended to use thread
sealant (Loctite 577 or similar) at the coolant connections to prevent loosening. Loosening can be
caused by vibration or temperature variations.
The electric machines are equipped with at least three PT100 temperature sensors in the windings.
The amount of the sensors depend on the options chosen. The temperature signal(s) can be read
out from the measurement connector of the machine.
You can connect the temperature signal to the temperature monitoring pin in the inverter (EC-C)
and make sure that the inverter has the machine temperature protection feature activated.
