Answer：CCTV reported that according to the Associated Press and CBS news, a document released by the National Highway Traffic Safety Administration on June 3 shows that more than 750 Tesla owners in the United States have complained about the use of Tesla v...
Answer：The AC current is induced in the armature winding of the DC geared motor. Through the mechanical action of the point brush and the commutator, the current flowing into the external circuit is a DC current. The so-called commutation is to use the mech...
Answer：New energy vehicles refer to vehicles with new technologies and new structures that use unconventional vehicle fuels as power sources. The popularity of new energy vehicles in the automotive industry is increasing day by day, and electric vehicles am...
Answer：Driven by the "dual carbon" goal, the prospect of new energy heavy trucks is bright, and sales will continue to rise. New energy tractors are widely used in the fields of steel, ports, and branch lines, and have become important models to rep
Answer：Introduction: Three- phase motor current imbalance may cause insulation breakdown of the motor. Whether the breakdown depends on the current in the motor windings. When the motor starts, the starting inrush current is very large. At this time, the ...
Answer：The DC motor is connected to the power supply through the commutator brush. When the current flows through the coil, the magnetic field generates a force, and the force makes the DC motor rotate to generate torque. The speed of the brushed DC motor i...
Answer：Three-phase induction motors are mainly used in computer peripheral equipment, lathe systems, photoelectric combination devices, valve control systems, nuclear reactors, surface grinders, CNC machine tools, automatic winding machines, electronic cloc...
Answer：Rotor windings are basically divided into two types: squirrel cage type and wound type. The squirrel-cage structure is relatively simple, and its windings used to be inlaid copper bars, but most of them are cast aluminum at present. The special doubl...
Answer：The motor shaft is a key component that directly bears the mechanical load. It must be able to withstand various alternating stresses without causing residual deformation and fatigue damage. For this reason, the shaft should have sufficient strength ...
Answer：A brushless DC motor (BLDC) is a type of permanent magnet synchronous motor, not a real DC motor, abbreviated as BLDC in English. Different from the brushed DC motor, the brushless DC motor does not use a mechanical brush device, but adopts a square ...
