A DC motor can be made using different types of armatures based on its application. There are 2 types of armatures. Gramme Ring Armature Drum Wound Armature Gramme Ring Armature …
We use 3 and 4 point starters in DC motors. What happens if a DC motor is started without a starter? Let’s check it. Consider a dc motor at standstill. When …
In this post, we will look at the voltage and power equation of a dc motor and the condition for maximum power in a dc motor. Voltage Equation of a …
Star-Delta starting is frequently referred to as “Soft-starting” a motor. But what is soft about his starting method? Why is it used? What are the advantages? What are the disadvantages? In …
In this post, we will look into the characteristics of a DC series motor. A DC series motor is one type of DC motor in which field winding is connected …
DC Motors works on the principle that they convert electrical energy (from a battery or voltage source) into mechanical energy (used to cause rotation). Are you thinking of making a …
Unlike Generators and Transformers, Electric Motors are rated in kW instead of kVA. We have already discussed why electric transformers are rated in kVA. This article explains why electric motors …
There are two types of DC motors – Brushed DC motor and Brushless DC motor. The direction of rotation of these motors is controlled by different methods. Brushed DC Motor …
Swinburne’s test is the simplest indirect method of testing dc machines. In this method, the dc machine (generator or motor) is run as a motor at no-load and losses of …
