High-torque stepper motors deliver precision motion control

EAO has introduced a new family of stepper motors that deliver 10% higher torque than currently available alternatives but produce 3dB(A) less noise with significantly reduced vibration and heat generation.

Improvements in motor efficiency has enabled manufacturer Sanyo Denki to boost the torque of its new Sanmotion SF24 Series of 42mm stepper motors by 10% compared to current equivalent sized alternatives but with 15% lower inertia. Together these benefits enable faster acceleration with reduced heat distortion, enabling ultra-precise equipment positioning.

The Sanyo Denki Sanmotion SF24 Series of stepper motors comprises four models each with a different motor depth, providing designers with a choice of holding torques ranging from 0.29Nm up to 0.8Nm, Single and dual shaft versions are available. All models feature a drive current of 1A per phase.

Manufactured using the latest automated motor winding, assembly and test processes the Sanmotion SF24 series of stepper motors are ideal for use in demanding applications such as medical inspection equipment and ATMs. The new devices are part of a stepper motor offering that ranges in size from14mm to 106mm. All Sanmotion stepper motors can be supplied complete with matching drivers and connecting cable and customized by the manufacturer to meet specific customer requirements.

GaN’s Ground-Floor Opportunity
The electronics industry has a major role to play in helping to save energy, by enabling better equipment and new ways of working and living that that are more efficient and environmentally friendly. Maintaining the pace of technological progress is key, but improvements become both smaller and harder to achieve as each technology matures. We can see this trend in the development of power semiconductors, as device designers seek more complex and expensive ways to reduce switching energy and RDS(ON) against silicon’s natural limitations.
