The analytical work on the principle of DC motor in the motor Limited by Share Ltd

The direct current motor adopts the structure of the star shaped folded plate, which not only has high space utilization, but also can withstand the fluctuating current and fast load current changes when the static rectifier is used. The DC motor is generally not a series wound winding, which is suitable for the automatic control technology which need to be positive and reverse. With a series shunt winding, the user can be required. Center height of 100 ~ 280mm motor without compensation winding, but center height 250mm, 280mm motor according to the specific circumstances and needs can be made with compensation winding, center height of 315 to 450mm motor with compensation winding. Center height 500 ~ 710mm of the motor form installation size and technical requirements are in line with the IEC international standard, the motor of the mechanical dimension tolerances in line with ISO international standard.

Working principle of DC motor:

DC motor coil connected to a commutator, the commutator fixed on a rotating shaft, between between the motor shaft to rotate together, and the reversing and reversing pieces and shaft over are insulated from each other, they constitute the whole known as the commutator. Brush is fixed in space.

In the DC voltage on the motor of the two brush end, due to the action of the brushes and commutator will power into the armature coil, and to ensure that the same pole coil current is always in one direction, then ensure that the pole coil of electromagnetic force in the same direction, to ensure that the motor can rotate continuously, in order to transform electrical energy into mechanical energy to drive the production machinery, which is DC motor working principle. Note: the current direction in the side of the coil is alternating.
