Precise Pumping Calls for Hybrid Steppers

From Portescap
 

 

Hybrid stepper motors make for a good choice when applications call for low-cost yet fine resolution of shaft movement, as in medical syringe and peristaltic pumps. The motors provide precise speed and motion control for analyzers, ultrasound scanning, X-ray equipment, and pick-and-place machines, but the focus here is on how improvements to hybrids help design better medical pumps. It's useful to start with a discussion about stepper motors in general and hybrids in particular.
Other stepper types besides hybrids are called can stack and variable-reluctance (VR) motors. All steppers work best in applications needing less than 3,000 rpm.
