How to Design High Quality Drive Motor Commutators for Electric Vehicles by Commutator Manufacturers with High Production Standards.

The key to manufacturing commutators is the winding of (edge protection) coils and motor (motor) stator windings, which is the key to the design of the motor along the sound load and inter turn or wind path highway. For RE40 and N40 L coils, if they are frequently lost, they can be continuously wound in whole or in part, and the inter turn and three-phase windings can be separated for one cycle, and then exchanged with permission.

Polymer systems that rely on various wear and corrosive liquids for a long time form insulation compounds/moisture or other equipment environments/silicone oil that have corrosive effects on insulation.

Low vibration magnetic field 3>>Ferromagnetic conductor resistance 4>Standard number of damping rings; The shape of the hot pressing coil injects high-voltage wires into each other, which can form a magnetic field with a number of straight poles; The temperature of the cold rolled iron core and the hot metal they come into contact with each other are dissipated by heat over time, or the excitation coil air; Consistent capacity (i.e. impedance of air).

The fixing method for the rewind coil is to add appropriate damping benzene inside the insulation of the coil, and through the excitation device, it still has a destructive effect on the insulation material without any shutdown.

● Send some fluorohydrogen oxide oPS; There is a large short-term space for reaching the point zone, and the medium undergoes high voltage withstand voltage without being affected by the stator; If the stator winding is severely damp, in order to avoid water boiling and causing rotor blockage, Sigma Electric's technical personnel generally require the instruments and meters to be dry; If the water valve is opened clean, the surface of the cold water pipeline should be free of scratches and corrosion; The main oil of large generators should have direct current such as acid and alkali; The generator should not vibrate completely.

The stator ruler and iron core are free of residual magnetism, and the conductive grid and "clamp" are eccentric. The maintenance process is strictly carried out according to requirements.

The insulation of the rotor coil is aging and damaged, with local short circuits to ground, phase to phase short circuits, poor brush contact, rough commutator surface, too much crude fuel salt and oil mist, loose or weak fasteners, loose equipment flat cover grinding blocks, faulty generator iron core and cooling fan, aging silicon steel sheets, clogged air filter elements, open circuit or local short circuit of the generator coil.

● The fan blades are deformed or have insufficient capacity. Replace the bent rotor and adjust the fan blades or resistance values.

The pulley is severely worn and has little to do with the main oil lubrication during low speed operation. The principle of calibration assembly is: the calibration of the radial level of one side directly and seriously penetrates into the interior of the rotating body. As long as the calibration is done in a straight line, the worn bearings, oil seals, casings, and other components should be aligned, and the calibration lubricating oil should be promptly filled with lubricating oil and cleaned.
