Inertia Dynamics PM Series Permanent Magnet Brake for Mobile X-Ray Cart
A global medical imaging systems manufacturer needed a reliable electric holding brake
solution for use on its newest mobile X-ray cart. The machine has many vertical, horizontal
and pivot movements including a collapsible tower, travel tube and scanning head that
a technician adjusts around the patient during set up. Once the ideal positions for each
section are established, the brakes are used to hold the cart and each component in place
to ensure crisp, accurate imaging.
The customer had explored the use of mechanical holding solutions that were not
very user-friendly. Ultimately, they contacted Inertia Dynamics (IDI) and shared specific
measurements that had been taken to identify how much force was needed to hold the
device at each of the movement locations. IDI engineers recommended the use of modified
PM Series permanent magnet brakes with different braking forces to meet the machine’s
various holding requirements.
The easy-to-use permanent magnet brake is released on-demand by the operator/medical
tech when positioning the X-ray scanner. Once in position, the operator simply releases the
switch to re-engage the brake and hold the device stationary.
IDI was able to quickly supply brakes for customer testing and then meet the customer’s
tight delivery schedule requirements for this very time-sensitive project. IDI’s permanent
magnet brake technology is ideal for use in medical equipment applications due to the
minimal backlash, high torque-to-size ratio, ease of installation and use, and generally low
cost in production volumes.
