Like servo motors, stepper motors are available in both rotary and linear designs. When an application requires force (rather than torque) output and can operate in open loop control, a linear stepper motor is often the preferred solution. Although linear stepper motors are available in both variable reluctance and hybrid designs, the more common version is […]
Linear Motors
Five key electrical design concepts for mechanical engineers
Edited by: Paul J. Heney, Editorial Director Mechanical engineers often overlook important electrical issues when specifying their respective parts of an electromechanical system. This targeted advice will help you design your next electromechanical system. Mechatronic systems are the state-of-the-art technology in automation systems, intelligently integrating mechanical and electrical elements to perform increasingly complex and demanding […]
FAQ: What’s the difference between variable-reluctance linear and hybrid linear steppers?
Linear motors come in different mechanical and electromechanical arrangements to satisfy the requirements of different applications. For example, brushless linear motors (capable of forces to 2,600 N or more) work well in heavy robotics or material-handing applications. Linear ac-induction motors output 2,000 N to satisfy heavy-conveyor parameters. In contrast, iron-core brushless linear motors deliver a […]
FAQ: How do linear stepper motors compare to familiar rotary types?
Stepper motors go into linear actuators in two different ways: Stepper motors that are traditional rotary motors couple to mechanical rotary-to-linear motion devices (often in the form of a threaded shaft that mates with traversing nut or carriage) to produce linear motion. In this actuator setup, the motor output shaft usually couples to the screw […]
New trends in electric motors: Efficiency, power density, torque
If there’s one trend that’s prevalent in motors of all kinds, it’s the theme of increasing performance, more specifically a trio of highers: higher efficiency, higher power density and higher torque density. These are incremental improvements in motor performance that are at least partly driven by the Department of Energy (DOE) energy efficiency requirements, said […]
