EMS has introduced the BS22-1.5 series, a spindle drive system designed for demanding linear positioning tasks, such as glass-fibre technology, optical filters, lens adjustment in optical systems and micro actuators for medical technology.

The BS22-1.5 series enables Faulhaber high-precision ball screws to be integrated directly with its range of DC-Micro motors, brushless DC-motors and stepper motors.

Using ironless rotor motor technology, high-resolution encoders and integrated motion controllers, the system is claimed to enable precise linear movements with minimum travel variations of just 5μm over the total travel.

Mechanical interface to the motors is achieved with a backlash-free coupling integrated into the ball screw.

Key features

  • Minimum travel variations of 5μm over the total travel
  • Stainless steel construction
  • Intermittent axial forces up to 500N
  • Speeds up to 125mm/sec with maximum efficiency of 89 per cent
  • Modifications, including screw length, modified ball nuts or special lubricants, available on request

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.
