of them have been subject to the type inspection) at specified speed and
4 Technical requirements
4.1 General
The drive motor system shall meet the requirements of GB/T 18488.1-2015 and
the followings.
4.2 Initial position angle
When the drive motor is equipped with a position sensor, the relative angular
relationship between the phase of the back electromotive force waveform of the
drive motor and the phase of the waveform fed back by the position sensor shall
comply with the requirements of the product technical documents.
The back electromotive force of the drive motor at the maximum operating
speed shall not be greater than the specified value of the product technical
documentation.
4.4 Tolerance of no-load back electromotive force
The deviation between the back electromotive force and the typical value at
rated speed shall not exceed ±5% between the drive motors of the same
specification and model.
4.5 Cogging torque
The cogging torque shall not exceed the value specified in the product
4.6 Torque ripple
The torque ripple shall not exceed the value specified in the product
specification.
4.7 No-load loss of drive motor system
The no-load loss of drive motor system shall not exceed the value specified in
the product specification.
4.8 No-load loss of motor
The no-load loss of motor shall not exceed the value specified in the product
specification.
temperature during the test must be recorded.
Drag the drive motor to rated speed and measure back electromotive force.
The temperature correction method is described in 5.3.
For factory inspections in mass production, the supplier and the purchaser may
agree on other methods to reflect the tolerance of no-load back electromotive
force for the inspection of this item.
5.5 Cogging torque
The test is conducted in the actual cold state.
Place the drive motor smoothly and randomly select 3 different rotor positions.
Read and record the value of the torch wrench when the rotor starts to rotate
without continuous rotation. Take the maximum of all torque values as the
cogging torque of the drive motor.
Other test methods agreed by both parties can also be used.
NOTE The torque value measured with a torque wrench is actually the sum of the friction
torque and the cogging torque. Because the cogging torque of the motor generally accounts for
a large proportion, the measured value can be substantially equal to the cogging torque.
5.6 Torque ripple
The test is conducted in the actual cold state. When the drive motor system is
specified in the product technical documentation, the rated voltage is applied to
the DC bus.
Select several points evenly on the circumference. Fix the rotor at each rotor
position. The controller applies a specified torque command. Test locked-rotor
torque separately. The difference between the maximum and minimum values
in the test value is the torque ripple.
The number of test points and the torque command value are agreed upon by
both parties. Recommended to use peak torque, rated torque, 10% peak torque
as torque command.
NOTE This method is only an approximate measurement method for torque ripple in non-
weak magnetic regions, and does not consider the effect of rotation-induced position sensor
feedback angle error.
5.7 No-load loss of drive motor system
The test is conducted in the actual cold state. When the drive motor system is
under normal electrical connection and cooling conditions specified in the
product technical documentation, the rated voltage is applied on the DC bus
and the drive motor shaft is not connected to the load.
Evenly take at least 5 speed points within the speed range, including the
these speed points.
After the test draw the relationship curve between loss and speed.
5.8 No-load loss of motor
The test is conducted in the actual cold state.
Drag the drive motor to the specified speed. Record the torque, speed and
power of the torque and speed sensor. The power value is the no-load loss of
the drive motor at this speed. Evenly take at least 5 speed points within the
speed range, including the maximum operating speed.
After the test draw the relationship curve between loss and speed.
The test is conducted in the actual cold state.
Use short-circuit conductors to short-circuit all windings of the drive motor as
close to the stator winding outlet as possible. Drag the drive motor to the
appropriate speed. Measure stator winding current at this speed. Evenly take
at least 5 speed points within the speed range, which must include the
maximum operating speed.
After the test, draw the curve of steady-state short-circuit current and speed.
5.10 Steady-state short-circuit current tolerance
The test method is same with 5.9.
Re-measure the back electromotive force of the drive motor that has been
subject to the reliability test specified in GB/T 29307 according to the method
of 5.3. Calculate the back electromotive force reduction before and after the
reliability test.
Or to characterize and test according to the methods agreed by both parties.
