Q & A: Motor Theory and Practice

What is the average AC induction motor life expectancy?

What is the average AC induction motor life expectancy? There are many factors that affect the life expectancy of an AC induction motor (or any electric motor). These factors can include input power problems, improper mechanical installations, malfunctions in the... read more

What is the difference between an AC motor and a DC motor?

What is the difference between an AC motor and a DC motor? While both A.C. and D.C. motors serve the same function of converting electrical energy into mechanical energy, they are powered, constructed and controlled differently. 1 The most basic difference is the... read more

What are thermistors and how do they limit inrush current?

What are thermistors and how do they limit inrush current? Inrush currents are peak currents that occur when power is first applied to a load and is due to low impedance in the power mains transformers or the filter capacitors of switching power supplies (e.g., D.C.... read more

What is electrical torque and mechanical torque?

What is electrical torque and mechanical torque? Electrical motor torque is proportional to the product of magnetic flux and the armature current. Mechanical or load torque is proportional to the product of force and distance. Motor current varies in relation to the... read more
