Hey there, I've got a distinction question on my exam that I cant answer and wondered if I could get some help. The questions are 1. review why a dc motor needs a starter 2. discuss the operation of a dc motor starter with the aid of a suitable diagram.
A DC motor does not use a starter. A car uses a starter.
When a DC power supply is connected to a DC motor then the motor will draw a high peak current as it starts running then the current decreases as the motor speeds up.
If the power supply cannot supply enough current for the motor to start by itself but has enough current for the motor to run then you must turn its armature manually to get it started.
