The commutator manufacturer tells you the structure of the commutator

The commutator manufacturer tells you that if there is no commutator, the motor can only turn less than half The ring is stuck and can only be used as an electric brake. The centrifugal force generated when the motor rotates is used as the power to control the starting resistance, thereby reducing the starting current of the motor and increasing the starting torque, so that the wound asynchronous motor can realize the brushless automatic control operation device.

The commutator manufacturer tells you that it is mainly composed of casing, starting fluid, moving plate, spring, terminal Column, safety valve, exhaust valve, etc. This fluid resistance starting has a small starting current, large starting torque and protection that automatically adapts to changes in power and load characteristics. Motor commutators are high-speed rotating equipment, and their rotor windings are affected by electrical and centrifugal forces, although always It is operated under the rated parameters, but the rise of the welding joints of the rotor winding and the commutator is the weak link of the commutator rotor, and the traditional welding process is used, combined with the DC resistance measurement results, to judge the commutator rotor winding and virtual looseness. The welding seam between them will cause the end wire fatigue, the contact resistance increase, the calorific value increase larger, accelerate contact oxidation, and make further contact resistance increase larger, The calorific value further increased, such a vicious circle, the rotor insulation of the commutator was burned at high temperature, and the arc was discharged to the ground, Damaged commutator.

The commutator manufacturer tells you that the commutator disassembly test results show that the test data and the rotor winding judgment conclusion is accurate. In addition to transmitting the longitudinal current, the motor commutator is also responsible for the current commutation of the short-circuit armature coil. These currents are reverse currents and reactive voltages generated when the main current motor commutator is running, causing the brushes to slide across the surface of the motor commutator causing edge sparks and arcing. The influence of the motor commutator on the motor function depends on the conduction process of the circuit when the commutator slides with the brush at a high speed under certain conditions. Although the description of this process is relatively complicated, and the theoretical research is still in the development stage, through the comparative analysis of the operating conditions of micromotors at home and abroad, it can be determined that wear is the key factor leading to the change of contact resistance.

commutator The manufacturer tells you that the functions of the electronic commutator include: the commutator mainly has various specifications such as hook type, groove type and flat type. Imported raw materials are selected and refined. The product performance has reached the international advanced level. Widely used in power tools, household appliances, automobiles, motorcycle motors and other fields. Slip ring, carbon brush holder, terminal board and other specifications and models. Used in automotive generators, gasoline generators and other fields. The commutator acts as a rectifier, and its function is to alternate the direction of the current in the armature winding to ensure that the direction of the electromagnetic torque remains unchanged. In a generator, a commutator converts an AC potential within the element to a DC potential across the brushes;In electrical thought, it can change the applied DC current to the AC current of the component, resulting in a constant torque direction.
