In modern motor testing, it is necessary to verify the performance of the motor for a long time. It is more important to verify the performance under load conditions and sudden changes in the load. Therefore, solving the load problem used in the oper...
Due to the different causes of over-voltage, the countermeasures adopted are different. For over-voltage during parking, if there is no special requirement for the stopping time or position, then the method of extending the inverter deceleration time...
Composed of a set of contact rods fixed on the rotating shaft of the machine, and connected to the armature winding is the commutator; when the shaft rotates, the commutator will reverse the flow of current in the winding, for a single electric Pivot...
The brushless motor has no brushes and commutator, and the positions of the magnet and the winding are opposite; the magnet is on the traditional motor shaft, the copper winding of the armature is fixed and surrounds the shaft, a small circuit board ...
First, let’s take a look at the operation of a simple alternator. The simple alternator consists of a single coil, which is supported and rotated between the two poles of a permanent magnet. Each end of the loop is connected to a conductive metal or ...
Most of the reversing equipment is used in harsh applications and harsh industrial environments, from the railway industry to steel mills and even naval submarines. The reversing equipment constructed of electronic materials is characterized by its e...
The rotor, bearing, stator, air gap, winding and commutator are all the basic components of the motor. The first four components are explained in detail below. Rotor: In an electric motor, the moving part is the rotor, which rotates the shaft to t...
