High-speed brushless motor enhances atherectomy procedures for medical device manufacturer

11th July 2023

Atherectomy procedures are one of the most effective ways to remove arterial plaque and improve patient blood flow. When a medical device OEM was searching for an alternative motor manufacturer for its atherectomy tool, it was vital that their new motion partner could optimise performance within the same form factor. With extensive experience providing motor solutions for handheld medical devices, Portescap was rapidly able to develop a customised solution, improving on the OEM’s original requirements.

Specifying a stepper motor: a guide to the key parameters

25th May 2023

Stepper motors are often perceived as more complex to specify and control compared to BLDC or brushed DC motors. However, their inherent positioning capability, converting electrical pulses to discrete ‘steps’, enables reliable incremental motion. Without the need for an external feedback device, this also aids simpler, and more compact, motion system design.

The impact of load on miniaturised motor selection

19th April 2023

When selecting a miniature motor, understanding the different loads acting on the motor is key to achieving the best design. Understanding torque load is essential to define the necessary motor power, while understanding radial and axial loads is required to achieve optimal performance and longevity through the most appropriate motion solution specification.
