Motors

A speed and torque rating is the starting point in selecting a motor once the initial constraints are determined. Size can also be impacted by minimum requirements for starting or stall torques and duty cycle. Read more...

Increasing the motor power needs an increase in electrical power. This is best done by using a higher voltage. Of course there will be an increase in current so a means of additional cooling will have to be added. Read more...

They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field. This force creates a torque on a loop of wire present in the magnetic field, which causes the motor to spin and perform useful work. Read more...

A generator converts mechanical energy into electrical energy, while a motor does the opposite - it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field. Read more...
