WebbA DC motor can be reversed by changing the polarity of both the armature winding and the field winding True or false False D.C. series motors can develop only about 125% of full load torque upon starting True or false False D.C. Series motors are used where constant or adjustable speed is required and starting conditions are moderate True or false WebbIn a DC motor, the magnetic field uses a rotating force or a torque over to the winding to rotate. On the other hand, in a DC generator, mechanical torque is applied in the direction of the shaft to maintain the armature winding motion. In both cases, commutators reverse the direction of current flow throughout the winding.
WebbThe armature windings conduct AC even on DC machines, due to the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors. The armature can be on either the rotor (rotating part) or the stator (stationary part), depending on the type of electric machine.

Webb21 apr. 2024 · The coils of wire are known as windings. The simplest DC motor has just a single coil. These are a simpler design; the problem though is that they can align magnetically which jams the motor and stops it from rotating. The more sets of coils we have, the smoother the rotation will be, this is especially useful for low speed applications. overcash dumpstersWebbCommutator.
