How do individual timers, which have only light, single-pole control contacts, control the acceleration steps of a large DC motor?
Explain the controlling process of acceleration steps of a large DC motor by individual timers that have only light, single-pole control contacts.
Explanation of Solution
A timing relay can provide a definite time interval that is used to control the acceleration of the DC motor when it is being brought up to a speed. Using the inserted resistors in the line ahead of the DC motor, the acceleration of the motor can be controlled.
A definite time interval is provided by a timing relay contacts, it means that the resistors remain in the line for a fixed time period before the DC motor is connected across the line...
