The first linear motor was conceived by Wheatstone more than 100 years ago. But large air gaps and low efficiencies prevented linear motors from being widely used. Though they still have relatively ...

Here’s how power losses and inertia matching affect the efficiency of linear drives. The operating efficiency of linear drives is of growing concern to machine designers. Here's a look at three common ...

Engineers who have designed motion control systems have most likely worked with pulse width modulated (PWM) drives. These drives are the default choice in most day-to-day motion control jobs, thanks ...
