After long-term operation of the DC motor, due to poor commutation, unreasonable brush arrangement and improper brush material, streaks, regular burns, pitting on the surface and uneven wear will often appear on the surface of the DC motor commutator...
The excitation winding of the DC motor is connected in parallel with the rotor winding, the excitation current is relatively constant, the starting torque is proportional to the armature current, and the starting current is about 2.5 times the rated ...
The commutator and the brush form a corresponding sliding friction pair in the motor. The influence of the commutator on the performance of the motor mainly depends on the electrical contact when the brush is sliding at a high speed under the conditi...
The new type commutator adopts an integral commutating piece, that is, the commutating piece with the rising piece is integrally stamped, which overcomes the problems caused by the welding of the rising piece and the commutating piece in the prior ar...
The commutator is a component of the DC permanent magnet string IP idea in order to keep the electric idea rolling. Structurally, the commutator is a circle with several contact pieces connected to each contact on the rotor. The two electrodes connec...
1. Chassis: Cast iron with high rigidity FC-25; 2. Gear: Made of high purity alloy steel 50CrMnT quenched and tempered, carburized, quenched and ground; 3. Spindle: It is made of high-purity alloy steel 40Cr quenched and tempered, and has high heavy ...
The motor commutator is a component of a DC permanent magnet series motor in order to keep the motor rotating. Structurally, the motor commutator is a circle with several contact pieces connected to each contact on the rotor. The two electrodes conne...
A motor with a commutator, because the commutator not only conducts current but also commutates, its monitoring workload is much greater. Frequent and careful observation of the status and characteristics of the commutation sparks is a very important...
