Electric Braking: Meaning and Types | Electrical Engineering

In this article we will discuss about:- 1. Meaning of Electric Braking 2. Types of Electric Braking 3. Advantages 4. Disadvantages and Limitations. Meaning of Electric Braking: If the load is removed from an electric motor and supply to it be disconnected, it will continue to run for some time due to inertia. The time elapsing before it stops will [...]

Braking: Applications and Control | Traction | Electrical Engineering

In this article we will discuss about:- 1. Introduction to Braking 2. Methods of Applying Braking 3. Systems 4. Mechanical Considerations 5. Control Equipment. Introduction to Braking: Electrical and mechanical, both types of braking are used in electric traction. In electric braking the braking energy is converted into electrical energy instead of converting it into heat energy at the break [...]

Regenerative Braking: Difficulties and Advantages | Electrical Engineering

In this article we will discuss about:- 1. Introduction to Regenerative Braking 2. Difficulties Encountered in Regenerative Braking 3. Calculations of Energy Returned during Regeneration 4. Advantages and Disadvantages. Introduction to Regenerative Braking: Regenerative braking is an inherent characteristic of dc shunt wound motors and does not require any change of connections. DC shunt motors are electrically stable also i.e., [...]

Types of Electric Braking Used in DC Motors | Electrical Engineering

In this article we will discuss about the types of electric braking used in dc motors. Plugging or Counter-Current Braking: In a dc motor a reversed torque is obtained by reversing the current either in the armature or in the field (not both), Polarity reversal of field winding is rarely used because it results in longer braking time due to [...]

Electrical Braking in Polyphase Induction Motors | Electrical Engineering

The following points highlight the methods of electrical breaking used in polyphase induction motors. The methods are: 1. Plugging (or Counter-Current Braking) 2. Dynamic (or Rheostatic) Braking 3. Regenerative Braking. Method # 1. Plugging (or Counter-Current Braking): Plugging can be achieved in an induction motor merely by reversing two of the three phases which causes a reversal of the direction [...]
