Speed Control Methods of Various Types of Speed Control Motors
A large number of motors are being used for general purposes in our surroundings from house-hold equipment to machine tools in industrial facilities.
The electric motor is now a necessary and indispensable source of power in many industries. The function and the performance required for these motors are wide-ranging. When focusing attention on the speed control segment of the motor market, servo and stepper motors control their speed with a pulse train, while the induction motor and the brushless DC motor control speed with an external resistor and/or DC voltage.
This article explains the structure, the speed control principle, and the features of the following three product groups that can control the speed relatively easily by using analog input...
