followings apply.
3.1 asynchronous drive motor system
a system composed of an asynchronous drive motor (hereinafter referred to as
the drive motor), a driving motor controller, a connecting cable, and an auxiliary
device necessary for the operation of the driving motor system (hereinafter
referred to as the drive motor system)
3.3 declared value of locked current
the average of locked currents of the first four drive motors (2 of them has been
subject to the type inspection)
4 Requirements
4.1 General
The drive motor system shall meet the requirements of GB/T 18488.1-2015, 4.2
and 4.3.
4.2 No-load current tolerance of drive motor
The drive motor runs at no load under the specified power frequency voltage,
the no-load current must not deviate from ±10% of the typical value.
5 Test methods
5.1 General
In addition to the test methods specified in 5.2 and 5.3, the test methods for
other test items shall be conducted in accordance with GB/T 18488.
5.2 No-load test of drive motor
The drive motor that performs the type inspection must be subject to the
measurement of no-load curve. The starting point voltage is 1.25 times the
specified voltage of 4.2.Then gradually reduce the voltage to the lowest
possible voltage (i.e., when the current begins to rise).
5.3 Locked test of drive motor
The drive motor that performs the type inspection must measure the locked
characteristic curve. Lock the drive motor rotor and apply the power frequency
voltage.
6 Inspection rules
The inspection rules are in accordance with GB/T 18488.1-2015.See Annex A
for the inspection items.
7 Marks and identification
In accordance with GB/T 18488.1-2015.
Annex A
(normative)
Inspection classification
The inspection is classified into exit-factory inspection and type inspection. See
Table A.1 for the inspection classification.
