What is a Compound Wound Traction Motor?

It is a Direct Current Motor which is wound and creates a magnetic field when energized and does not use a permanent magnet. Jeff S.


If a wire with no current passes a magnetic field of flux will voltage be induced into the wire?

Yes, for as long as the magnetic field is moving along the conductor. A static magnetic field will not induce current, a dynamic field is required.


What is an armature brake?

An armature brake is a type of braking system used primarily in electric motors and generators. It functions by creating a magnetic field that interacts with the armature, generating a counteracting torque that slows down or stops the rotor's motion. This braking method is efficient and allows for precise control of speed and positioning in various applications, including electric vehicles and industrial machinery.


What is the principle of operation of a repulsion motor?

A repulsion motor operates on the principle of electromagnetic repulsion between the stator and rotor. When the stator is energized with alternating current, it creates a rotating magnetic field that induces current in the rotor. This induced current, in turn, generates its own magnetic field, which interacts with the stator's field, resulting in a repulsive force that causes the rotor to rotate. The motor typically requires a commutator to ensure that the rotor's magnetic field is properly aligned for continuous rotation.


What is hold in winding?

Hold in winding refers to the specific winding configuration in an electromagnetic device, such as a relay or solenoid, that maintains the position of the armature or movable part when the device is energized. This winding generates a magnetic field that keeps the armature in place, preventing it from returning to its default position until the power is removed. The design ensures that the electromagnetic force is strong enough to hold the armature securely during operation.

Is the temperature field map a static or dynamic field?

The temperature field map is typically a static field since it represents a snapshot of temperature distribution at a specific point in time. However, the temperature field can be dynamic if it changes over time due to factors such as heating, cooling, or air circulation.


What is meaning of dynamic elements in electronics?

Dynamic element term is arises on the domain of digital to analog conversion in the field of electronics. if you are looking for dynamic microphone it means this converter applied sound vivration to electrical signal. Dynamic term also arise in the field of diode static and dynamic resistance.

dynamic and static


What is dc injection braking for ac motors and how does it work?

works with the concept of DC injection braking, where a dc volt is injected into a three phase rotating magnetic field which causes a stagnet magentic field thus bringing the motor to a complete halt.


Do anti-lock brakes reduce braking?

Most experts in the field agree on this. ABS does reduce braking distance on dry or wet pavement if they are used properly. On gravel and snow ABS may increase braking distance slightly. But ABS's main safety feature is not to decrease stopping distance, but is to allow control of the vehicle during an emergency stop, because it prevents wheel lock-up and a skid.

What field areas use dynamic range?

The field areas in wide dynamic range are from shadows to highlights. The term is use to describe the contents of an image file containing such data and the capability of a sensor or other imaging system.

What electromagnetic device has a magnetic core and an energized cell?

An electromagnet typically has a magnetic core, such as iron, and is energized by running an electric current through a coil wrapped around the core. When the current flows, it generates a magnetic field around the core, giving the electromagnet its magnetic properties.
