Surgical Robotics Technology Covers ThinGap As a Motor Leader

ThinGap has been covered in Surgical Robotics Technology as a leader regarding high-performance motor solutions for surgical robots.

Robert Mastromattei has showcased ThinGap’s frameless motors as being the ideal solution for high-precision surgical robotic applications in his latest publication on the website. After analyzing desired motor performance, focusing on characteristics such as zero-cogging, and large internal diameter, ThinGap’s LS series of motors are presented as the best solution for high-precision surgical applications.

Mastromattei details:

“A traditional frameless motor is shown below. The motor shown in Figure 2 is a slotless LS Series motor from ThinGap.  These motors have zero cogging and a large through hole. Km of these motors rivals some traditional slotted (or toothed) brushless permanent magnet motors.

Figure 3 below is a compact integrated Robot Joint for Surgical Robotics. It uses a frameless torque motor kit, high resolution medium accuracy absolute encoder on the input. It has a high ration zero backlash precision gear and a high accuracy absolute encoder on its output.”

ThinGap’s LS Series of slotless motor kits range in size from 25 to 267 mm outer diameter and continuous torque from 0.1 to 12.0 N-m. The LS motor offers torque performance equivalent to traditional frameless motor kits available on the market, unlike other slotless motor solutions which force a tradeoff between torque output and smoothness. With standard and modified standard configurations, the product line will cover voltages from 7-285 volts and current from 3-12 amps.
