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.
What type of rotor is found in a universal motor?
Wound rotor and squirrel-cage rotor
What is the correct fuse rating to provide short-circit protection for a 100HP 200V 3-0 wound-rotor motor?

Are wire wound resistors used in parallel circuits?
Can be. Wire wound resistors might take more power, or offer better precision, or custom resistance values. Wherever, whenever those features are desirable, whether its a series or parallell circuit, a wire wound resistor might be used.
Which motor has a higher starting torque?
A series-wound commutator motor has the best starting torque because the torque is proportional to the square of the current, and the starting current is set by a current-limiting resistor which is switched out as the motor builds up speed.
What different types of DC motor are there?
Series wound. Parallel wound. Series/parallel or Compound wound.
Dc machine having wave winding is wounded as lap winding what will be the effect on emf generated?
Emf generated=(flux*no.of parallel poles*no.of conductors*speed)/(60*no.of parallel paths) therefore, for lap wound.... no.of parallel path=no.of poles and wave wound ..... no of parallel path=2
What type of DC motor used by fan?
DC motors are commonly used in cars and normally run on 12 v. DC motors can be broadly classified as series-wound and parallel-wound and for fans the parallel-wound version is used with the field winding placed in parallel with the armature (for domestic use AC fans using induction motors are normally used).
Basic principle of commutator motor meter?
It is based dynamometer principle with ironless motor with a wound armature having a commutator. The two coils are connected in series with supply and armature coil is connected in parallel to it.
Explain starting of a wound rotor induction motor?
explain wound rotor

To replace 7.5 kw 400dc1750 rpm motor with an equivalent ac motor which produce eq. torque then what should be the rating of motor?
What kind of DC Motor? Different motors have different torque DC Motor Types * Permanent Magnet: No field coils at all. * Series Wound: the field coils are connected in series with the armature coil. Powerful and efficient at high speed, series wound motors generate the most torque for a given current. Speed varies wildly with load, and can run away under no-load conditions. * Shunt Wound: the field coils are connected in parallel with the armature coil. Shunt wound motors generate the least torque for a given current, but speed varies very little with load. Will not run away under no-load, but may if the field windings fail. * Compound Wound: a combination of series and shunt wound. This is an attempt to make a motor that will not run away under no load or if the field fails, yet is as efficient and powerful as a series wound motor. * Check this link: http://www.reliance.com/prodserv/motgen/b7096.htm
What is difference between stab shunt dc motor and shunt dc motor?
A series motor respond by decreasing its speed with small increase in current for a given load torque. A shunt motor holds its speed nearly constant with large increase in input current for same amount of load torque
After surgery does cell growth increase or decrease as wound heal?
beacuse it increase as the cells are multiplying so that to form new tissues and thus new skin to replace the wound
Why are guitar strings wound?
Guitar strings are wound to increase their mass and density, which helps produce a richer and fuller sound when the strings are played.
What type of rotor is found in a universal motor?
Wound rotor and squirrel-cage rotor
Does cell growth increase as the wound heals?
Yes, cell growth is a key part of the wound healing process. As the body works to repair the damaged tissue, new cells are formed to close the wound. This cell growth helps to restore the integrity of the skin or tissue that was injured.
