PRODUCT DESCRIPTION 11
The electrical performance data on the rating plate is only valid if the motor is connected to a liquid
cooling system. The requirements of the liquid cooling system are shown on a separate rating plate
located on the motor, see Figure 1. An example of a separate rating plate can be seen in Figure 3.
Figure 3. Example of separate rating plate with liquid cooling system data.
2.2. Expected lifetime
The expected lifetime is very dependent on the motor´s winding and bearing temperature. The lower the
temperature the longer expected lifetime. The insulation system for the motor is class H, which means
that the winding temperature should not exceed 180°C. If the winding temperature is kept below this
limit, the expected lifetime of the insulation system is at least 20,000 hours. The electrical performance
data on the rating plate, see Figure 2, is the continuous operation point (S1). Operating in this point will
not compromise the expected lifetime. As a simplified method, the S1 power in a duty cycle can be
calculated by the root mean square method:

The electrical performance data on the rating plate is only valid if the motor is connected to a
cooling system. The requirements of the cooling system are shown on a separate rating plate
located on the motor, see Figure 1. An example of a separate rating plate can be seen in Figure 3
Figure 3 Example of separate rating plate with cooling system data
2.2 Expected lifetime
The expected lifetime is very dependent on the motor´s winding temperature. The lower the
temperature the longer expected lifetime. The insulation system for the motor is class H, which
means that the winding temperature should not exceed 180°C. If the winding temperature is kept
below this limit, the expected lifetime of the insulation system is at least 25,000 hours. The
electrical performance data on the rating plate, see Figure 2, is the continuous operation point (S1).
Operating in this point will not compromise the expected lifetime. As a simplified method, the S1
power in a duty cycle can be calculated by the root mean square method:
 =1

=
So, in a duty cycle, the rated torque and power on the rating plate could exceed the short term
(peak torque and peak power) as long as the winding temperature do not exceed 180°C.
As mentioned in the Product description, the motor is equipped with temperature sensors in the
stator winding. In most inverters, it is possible to set a warning limit and a shutdown limit for the
winding temperature. To not compromise the expected lifetime, the values in Table 2 are
recommended.

The expected lifetime for bearings and external seals is not solely temperature dependent and
needs to be evaluated based on the duty cycle. Please contact your local ABB sales office for
technical support.

So, in a duty cycle, the rated torque and power on the rating plate could be exceeded short term (peak
torque and peak power) as long as the winding temperature do not exceed 180°C.
As mentioned in the Product description, the motor is equipped with temperature sensors in the stator

lifetime.

3. Transportation and Storage
3.1. Transportation
3.1.1. Delivery to customer
The motor is transported fastened to a pallet. Leave the motor on the pallet until it is time to place it in
its working place, i.e., chassis.
During short term storage, place the motor so that it is out of the way of any other goods being handled,
and on a flat, vibration-free surface.
Figure 4. The motor is delivered on a pallet.
3.1.2. Inspection of delivery
Unpacking should be done carefully in order to avoid damage. The delivery should be checked against the
packing list.
NOTE: When the motor arrives at its destination, be sure to check the motor in order to determine
possible transport damage as quickly as possible. Any damage during delivery or deviations
from the packing list should be entered in a report and the transport company contacted.
If the motor has suffered damage during transport or installation, this must be rectified before
commissioning.

TRANSPORTATION AND STORAGE 13
3.1.3. Lifting of motor
Warning - Heavy Components
Risk of personal injury when lifting the motor.
The weight of the motor is visible on the rating plate.
Only skilled and trained personnel should carry out dismantling.
NOTE: The lifting eye bolts are not included in the delivery as standard.
The lifting eye bolts must be dimensioned to handle the motor weight.
NOTE: Check that the lifting eye bolts are undamaged before lifting. Damaged lifting eye bolts
must be replaced before lifting.
Lifting must be performed with great care and using appropriate equipment. When lifting the motor, it is
important to lift it in a way that does not affect any critical part such as the bearings, shaft or connection
box.
There are several holes at 3, 6 and 9 o´clock seen from the D-end where the lifting eye bolts should be
attached depending on the mounting. One example is shown in Figure 5 below. Always use these holes
when lifting the motor.
Figure 5. Position of lifting eye bolts.

MOTORS FOR HEAVY ELECTRICAL VEHICLES
14
The angle between the lifting chains shall be a maximum of 60°, see Figure 6.
Figure 6. Lifting of motor.

TRANSPORTATION AND STORAGE 15
3.2. Storage
Measures to be taken by the customer or other part:
• The motor should be left on the pallet.
• The pallet with the motor should preferably be stored indoors and shall be placed on a vibration-free,
flat and well-drained surface.
• The pallet with the motor should be kept dry, dust-free and protected from rain and moisture.
• If the motor is equipped with heating elements in the stator winding, ensure they are electrically
connected to prevent possible condensation.
• It is recommended that the shaft is rotated monthly to prevent grease migration.
• All motors leave the factory with an anti-corrosion coating, such as Tectyl 506, on the shaft extension
and mounting surfaces. The coating should be inspected by the customer and re-applied if necessary.
3.3. Removal of Tectyl before commissioning
The corrosion protection coating, such as Tectyl 506, must be removed before commissioning. Ensure
that corrosion protection coating is removed for mating surfaces, e.g., shaft and flange surfaces. Tectyl
506 can be removed with Tectyl HPS solvent borne thinner, vapor degreasing, a hot alkaline wash or low
pressure steam.
3.4. Insulation resistance check
Measure insulation resistance before commissioning, after long periods of standstill or storage when
winding dampness may be suspected.
Insulation resistance should be used as a trend indicator to determine changes in the insulation system.
In new motors, the insulation resistance is usually thousands of MΩand thus following the change of
insulation resistance is important in order to know the condition of the insulation system. Typically, the
insulation resistance should not be below 10 MΩ(measured with 500 V DC and corrected to 25°C). If the
reference resistance value is not attained, the stator winding is too damp and must be oven dried. Please
contact your local ABB sales office for technical support.
NOTE: To avoid risk of electric shock, the motor frame must be grounded and the windings should
be discharged against the frame immediately after each measurement.

4.1. Mechanical installation
4.1.1. Preparation and lifting
Remove the anti-corrosion coating.
Always use the holes for the lifting eye bolts when lifting the motor, see Figure 5 and Figure 6.
4.1.2. Installation of coupling
To ensure low noise and vibration levels, the alignment between the motor shaft and the mating coupling
must be accurate. The higher the motor operating speed the higher accuracy is needed. The figure below
illustrates the concentricity and perpendicular demands for the mating coupling.
Figure 7. Geometrical tolerances for the mating coupling for B14 and B5 mounting.
The values for X and Y depending on motor operating speed could be found in Table 3.

exposure to the coolant.
Information about pressure drop as a function of flow rate and how glycol mixture affects performance is
found in the motor data sheet. The product code is visible on the rating plate, see Figure 2.
NOTE: Ensure that the specified data on the separate rating plate, see Figure 3, is fulfilled before
operating the motor.

MOTOR INSTALLATION IN VEHICLE 19
4.3. Electrical installation
The motor needs an inverter to operate. The inverter must be able to supply 3 phase AC current and be
capable of controlling the motor. The motor has been tested and optimized together with the ABB
HES880 inverter. An inverter with a different control strategy, switching frequency and pulse pattern
might have an impact on the motor performance. For more information about the HES880 inverter,
please contact your local ABB sales office.
