Difference between Stepper Motor and DC Motor
Stepper motors have more pole counts, generally between 50 and 100. whereas Servo motors have a low pole count – between 4 and 12. An electric … Read more
Machines
An electrical machine converts mechanical energy into electrical energy or vice versa. The transformer is also an electrical machine which transform the voltage without changing the frequency. We will discuss about the;
- DC Motor
- DC generator
- Induction Motor
- Transformer
- Electrical drives
- Alternator or synchronous generator
