Question
Dear Prof Steve

1 Is it possible to achieve
Reciprocating Motion in Electric motor
i. e. Moving forward and backward in straight line apart from the conventional rotary Motion of Electric motor?.

2 If yes, Can there be advantages in designing electrical products which have a reciprocating Motion for the Electric motor?.

Thanks
Prashant

Answer
Hello Prashant,

1. I don't understand what you mean by "Moving forward and backward in straight line". I will interpret this as if the motor drive is connected to wheels that the device sits on and the forward and backward refers to the motion of the device.
Yes. The brute force way would be to include a crankshaft like in an auto's engine. A more precise(and expensive) way would be to use a stepper motor.

Notice that it increases the complexity of the drive signal significantly.

2. The advantage is in occasions (of which there are many common examples) in which reciprocating Motion is required.

I hope this helps,
Steve

Expertise

I would be delighted to help with questions up through the first year of college Physics. Particularly Electricity, Electronics and Newtonian Mechanics (motion, acceleration etc.). I decline questions on relativity and Atomic Physics. I also could discuss the Space Shuttle and space flight in general.

Experience

I have a BS in Physics and an MS in Electrical Engineering. I am retired now. My professional career was in Electrical Engineering with considerable time spent working with accelerometers, gyroscopes and flight dynamics (Physics related topics) while working on the Space Shuttle. I gave formal classroom lessons to technical co-workers periodically over a several year period.
