the loading arrangement used in normal electrical machines is brake drum - spring balance arrangement. This is used to calculate the torque and output power.
the formula for torque is 9.81*(diffference between the spring balance) * radius of brake drum.
thee output power obtained is 2*π*motor speed*torque obtained
A belt moving over this break drum provides necessary torque to the shaft of the motor, and in turn loads the shaft with a finite torque. Two calibrated spring balances are connected to either side of the belt, which is moving over the break drum
higher power motors will have a bigger diameter shaft to easily handle more torque
no different from ac
Dc motors have much higher torque at low speeds which is why they are used in hand tools and locomotives
what is the loading arrangement in dc shunt motor
dc series motor is used for traction...
describe how to use starting resistors to star a DC motor
Dc shunt motor is constant speed motor.Its speed is constant with armature current.This shunt motor is used in paper mills and drilling machines
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
6V dc motor
dc series motor is used for traction...
on adding load on a dc shunt motor, the amount of current and torque will increase. but terminal voltage will decrease
The DC compound engine is a blend of the arrangement engine and the shunt engine. It has an arrangement field winding that is associated in arrangement with the armature and a shunt field that is in parallel with the armature.
Yes it can and the otherway aroud a DC motor can be used as a dynamo
yes dc motor is used in textile mills for presicion control.
universal motor
stepper motor :- motor used for controlling direction of movement of robotic arm dc motor :- motor used in cellphones as vibrators ac motor :- motor used in textile machinery
batteries are only used for DC CIRCUTS. if the motor is a DC MOTOR you can.
Synchronous motor or induction motor
describe how to use starting resistors to star a DC motor
DC Traction Motor.
I've not heard the term "bressless" - I think you mean "Brushless" - which is a DC Motor that does not use the usual commutator/brush arrangement. For a great answer to this question, see the Wikipedia article in the related links section.
