Piezomotor’s Piezo Legs one-piece walking machine is about the size of an ant but almost 1,000 times stronger.

Its four legs can elongate and bend when electrically activated.

By electrically pairing the legs and observing the transition and sequence of movement, two legs remain constantly in contact with the secondary interface, resulting in propulsion of this part.

Piezo Legs is available in different constructions so that a linear or rotary movement can be achieved.

As the motor relies on friction and the legs remain in contact with the interface at all times, high torques can be achieved without the need for a supplementary gearhead.

As a consequence, no unwanted backlash is introduced into the system.

The result is a motor that delivers a step resolution of one nanometre in the linear format and 25 Nanorads in the rotary format.

The friction element ensures the motor remains self-locking, with no power applied, making them ideal for handheld battery-powered devices.

Piezo technology uses few parts and only elementary motion.

Using Piezo motors removes the need for supplementary components, simplifying design and extending lifetime.

EMS (Electro Mechanical Systems)

EMS was founded in mid-1985 and quickly established itself as the leading supplier of high-quality precision small DC motors and linear actuators. We are sole UK distributors for the whole Faulhaber Group, including Minimotor, Precistep, MPS and Piezomotor; manufacturers and suppliers of precision micro-drives, including DC motors; brushless motors; stepper motors; linear motors and associated gearheads and encoders.

Complementary products include iron-core DC motors from KAG, stepper motors and brushed DC motors from Nidec Servo and brushed and brushless gear motors from Nidec Motors & Actuators. In addition we distribute high quality linear actuators and telescopic columns from SKF and Mingardi, used extensively in medical; healthcare; agriculture; building automation and many other industries.

With sustained growth we looked to diversify our product offering and in 1990 established our own manufacturing facility. Growth has been maintained with repeated expansion culminating in the acquisition of an eighth unit in 2010 resulting in an overall floor area to 2,200m². We have a large capacity machine shop equipped with the latest CNC machine tools and a dedicated gear cutting suite, as well as substantial assembly area. EMS offers design engineers a complete service; our scope of supply stretches from the supply of proprietary motors, gearheads, encoders and actuation devices, right the way through to added value in the way of pinions and wiring looms, to bespoke design and manufacture of complete drive mechanisms and actuation systems to meet your exact applications needs.

Located across two sites, our Head office, design and manufacturing is based in Poole, Dorset and sales, order processing, administration and warehousing located in Aldermaston, Berkshire.

Our commitment to quality and service remains as strong as ever and is reflected in our management system and strong emphasis on continuous improvement, resulting in our accreditation to EN ISO9001:2008 at both sites.
