Piezo motors challenge traditional technologies
Published:  29 January, 2019

The global market for piezoelectric motors was worth $8.3bn last year and will reach $12.5bn by 2027 – a CAGR of 4.7% – according to a new study from the analyst Fact.MR. It reports that more than two billion piezo motors were sold last year (about a quarter of them linear motors) and says that the market is being driven by factors including the motors’ high torque and force capabilities.

Another driver is an increasing interest in miniature, high-accuracy positioning systems for applications such as semiconductor testing and robot positioning. The analyst expects demand for ultrasonic piezo motors to witness steady growth in the future, emerging as an alternative to traditional motors, especially where high speed and efficiency are required.

The study also predicts that linear piezoelectric motors are going to take market share from rotary devices, because of their fast response, high accuracy, flexible design, low maintenance and high mean time between failures. It reports that manufacturers are designing linear piezoelectric motors for OEM applications with a focus on precision positioning and low energy consumption.

One application area proving particularly successful for linear piezo motors is in medical technologies such as pumps for drug delivery, artificial fertilisation, 3D scanners and micro-monitoring. Manufacturers are developing standard and non-magnetic linear piezo motors for medical applications following FDA and EU approval for mechanical-electronic devices.

PI (Physik Instrumente) is one of the market leaders for piezoelectric linear motors

According to Fact.MR, the front-running suppliers in the piezo motor market include Faulhaber, PI, Nanomotion, PiezoMotor, Attocube and Cedrat. The largest regional market for piezoelectric motors is North America, which accounts for almost 30% of global demand.
