What Is DC Motor?

DC motors receive direct current as an input and convert into mechanical energy. Such as these motors receive the electrical power and, in return, change into the automatic rotation as an output.

The machine contains a constant speed of rotation with a medium speed of torque, so it has a wide range of applications. Such as the DC motor is highly applicable in centrifugal machines and Reciprocating pumps. Due to its optimum speed and medium torque are also significant for various instrumental machines such as blowers,  fans,  and other lethal machines. The device also contained the feature of a custom layout, such as inserting the element according to your choice in the machine.

What is DC Motor
Construction and Structure of IE5 Series Motors

Construction and Structure of DC Motor

  • The base of the motor is laminated, comprising a thin octagonal steel plate. This structure makes the higher space utilization of the stator, compact internal structure, little input of the inertia, reduced body weight, and the strong ability to control the power supply by Silicon-controlled rectifiers.
  • Compensation windings are inserted inside the motor, with remarkable computing performance and overload capacity.
  • DC Motors own the F-class insulation, which has been treated by solvent-free VPI (Vacuum Pressure Impregnation) technique. The higher mechanical strength and the insulation performance are because of winding insulation.
  • The commutator possesses a vertical-plate type structure. The tungsten inert gas (TIG) welding helps connect the vertical plate  (commutator) and the armature coil.
  • The reduced vibration of the DC motor is attributed to the chute structure of the armature core.
  • The continuous working of the motor can be obtained by using rolling bearings and non-stoppable fuel addition.

Features of DC Motor

  • The rated voltage in a DC motor varies and can also be inserted according to your need. But the minimum range in the device is 220 Volt to 440 Volt, and so on.
  • The device expresses a separate excitation mode. The required voltage for the excitation of the device is 180 Volt to 310 Volt. Other quantities of voltage can also be adjusted in the machine.
  • At the initial speed of the machine, it rotates according to the speed-torque present on its technical sheet. Each turn of the torque lasts about 60 seconds.
  • The rated voltage for a motor is about 220 Volts. If you want to increase the device’s speed, its voltage will double. This dual voltage will also impact its torque speed, which will become about 1.8 times more. This quantity of torque lasts for 15 seconds.
  • As the DC motor works on the voltage of 220 Volt, this voltage is mainly for  Field weakening speed as on the technical Datashe, the quantity of torque will become 0.6 times that will last in about 15 seconds.
  • DC motors can reach the rated current change of about 200 to 250 times at an optimal rate. But if you want to increase it to more than 250, you can call our team, and we can adjust it according to your need.
  • The standard outlet of the machine during your ordering is mainly on the right side of the outlet box. But if you want to change its position to the left, you can call us before ordering.
