Maximum turn-on adjustment rate ()
】h rated fully enclosed motor or continuous rated external ventilated motor, its excitation Ampere ratio is about 50, parallel excitation (or compensation excitation) Ampere turns 50, series excitation turns (series excitation turns are the nearest integer) 5.6 Due to the speed change caused by heating
During the specified operating period, the speed change from cold full load to hot full load, full For enclosed motors, the rated speed should not exceed 20%; for externally ventilated motors, the rated speed tolerance should not exceed 15% of the rated speed. 5.7 Rated speed tolerance
Under normal operating temperature, rated load, rated voltage and rated brush current, the speed tolerance of the motor is ±7.5% of the rated speed.
5.8 Lead wire or terminal box
The position of the lead wire or terminal box of the motor should be on the side of the motor from the transmission end (i.e. non-commutator end). When the motor has a terminal box, the axial position of the terminal box is past the center line and close to the commutator end. When there is no terminal box, the relevant dimensions of the lead wire are shown in Table 1. 5.9 Rotational direction
The motor should be able to run in any direction,
5.10 Axial motion of the armature
The axial motion of the armature shall not exceed 5 m. 5.11 Others
Any requirements not specified in this standard shall comply with the provisions of GB755: 6 Inspection rules
6.1Each motor shall be inspected and qualified before use! And a product inspection certificate shall be attached. 6.2Test items and test methods of motors: The test items of motors shall comply with the provisions of GR/T755, and the test methods shall comply with the provisions of GB/T1311, but the following provisions shall be followed when conducting the various tests:
a) Rated load test: The test time for continuous rated and intermittent cycle duty motors is 1h. For intermittent cycle duty motors, rated load tests shall be carried out according to the short-duty duty system, and the test time for short-duty duty motors is the short-duty duty time. Commutation check after rated load test: when the motor changes from no-load to rated load and from base speed to high speed (including reverse when weakening the magnetic field or increasing the output pressure), the commutation spark level should not exceed 1 level; b) Short-time over-torque test: the test time is 15s, the torque value is in accordance with the specifications of the maximum operating torque in Table 3, and the commutation spark level should not exceed 2 levels;
) The motor should be able to withstand a short-time increased voltage test under no-load, the test voltage is 130% of the rated voltage, but should not be less than 600V, the test time is 3min, and no failure occurs; JB/T8163
d The insulation dielectric strength test of the motor winding to the casing and the windings between each other: the test voltage of the motor is 2000V, and the test time is 1 min.
