Non-Magnetic Motors
Piezo Motion has the ability to modify any current catalog motor to remove some or all the ferromagnetic material in it making the motors useable in applications where electromagnetic interference (EMI) is a critical requirement. Our motion technology leverages piezoelectric ceramics that deform at certain excitation frequencies. This means that we can create motion without the need for electromagnetic fields which are highly susceptible to EMI as well as polluting the environment with EMI. These principles can also be used in a ground-up design that can be a turn-key solution for your application. If you have any further questions in regards to our non-magnetic motor capabilities reach out to us directly.”
While most stepper motors have a maximum of 400 steps per revolution, a Piezo Motion rotary piezo motor has ~625,000 steps in a single rotation with each at full torque, stepping in 10 µrad increments.
Within 30 to 50 µs, the piezo motor has made its first step and motion has commenced, compared to a stepper motor with a typical 15 to 20 ms to start motion.
The rotary piezomotor contains no ferrous materials and is completely non-magnetic. Immune to EMI and RF interference and with no emissions, the RBS-50 is ideal for a range of sensitive and specialized applications (including MRI).
Piezo Motion’s rotary motors consume zero power at holding torque and very low power at slow speed yielding the possibility of very efficient overall duty.
These motors contain no copper windings, magnets, or ferrous laminations making it ideally suited to weight-critical applications. Our motor housings are lightweight, reinforced thermoplastic, and the motor operates at ultrasonic frequencies, making it virtually silent.
