Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...

In industrial automation, harmonic drive actuators are gradually replacing the traditional configuration of harmonic drive ...

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...

One of the more critical decisions engineers can make when designing any type of motion control process is choosing the motor. Getting the right motor, both in terms of type and size, is imperative to ...

Step motor control offers a powerful alternative in the right applications. Step motors are popular first and foremost because they are easy to use. They do not require an encoder to maintain their ...

The automation engineers of the 1960s would look with envy at the servo technology in use today. Small, precise, and, above all, electric, they are a reflection of the compactness of the semiconductor ...
