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 ...
Answer:The German Federal Government launched the Smart City Demonstration Project in 2021 with the aim of developing and exploring cross-sectoral digital strategies for future urban life. The German federal government has continued to invest 820 million eu...
