DC Motor Soft Starter

A brushed DC motor is an internally commutated electric motor designed to be run from a direct current power source. Brushed motors were the first commercially important application of electric power to driving mechanical energy. Brushed DC motors can be varied in speed by changing the operating voltage or the strength of the magnetic field.

Detailed Description for DC Motor Soft Starter

The DC motor soft starter generates torque directly from DC power supplied to the motor by using internal commutation, stationary magnets, and rotating electrical magnets. Advantages of dc motor soft starter include low initial cost, high reliability, and simple control ofdc motor soft starter speed. Disadvantages are high maintenance and low life-span for high intensity uses. Maintenance involves regularly replacing the carbon brushes and springs which carry the electric current, as well as cleaning or replacing the commutator. These components are necessary for transferring electrical power from outside the dc motor soft starter to the spinning wire windings of the rotor inside the dc motor soft starter. 


Starting Type:

-          Current Limiting Type: Limiting starting current, reduce starting voltage. Can be adjusted according to demand.

-          Ramp Voltage Type: Start motor smoothly and gradually to reduce the impact on the grid caused by starting current, to prolong the operation life of mechanical transmission.

-          Heavy-load Starting Type: Big start up torque

Stopping Type:

-          Normal.

-          Softstop

Control Type:

-          Input: Passive switch singnal

-          Output: Relay

The dc motor soft starter parameters and size can be modified according to customer requirements. We produce dc motor soft starter through the high temperature test, high temperature 120 degrees Celsius for 48 hours, and the low temperature minus 40 degrees Celsius for 48 hours.
