An ultra-thin ‘pancake’ stepper motor been launched by motion control specialists, Sanyo Denki, and is available in the UK from EAO. With a depth of just 11.6mm, the San Motion F Series 2-phase stepper motor comes in an industry-standard 50 and 42mm frame size. It’s also very light - only 0.09kg - and despite its compact proportions, it still produces a holding torque of 0.083Nm, increasing to 0.24Nm for the thicker 33.98mm version.
The high-resolution 1.8° step-angle provides excellent control over positioning. It is offered as either a unipolar or bipolar unit.
The relatively high torque and compact storage makes it ideal for new designs in space-critical applications, particularly within the semi-conductor processing industry, and for medical inspection equipment, surveillance cameras and instrumentation.
