Faulhaber has announced the latest addition to the BX4 series of high torque brushless DC servomotors.

The type 2250 remains only 22mm diameter but offers increased length, peaking at 35W continuous operation.

The modular construction eliminates complex manufacturing processes and delivers a versatile drive system, free from all adhesives.

The series is completed with a magnetic encoder, integrated speed controller, planetary gearhead, as well as external drive electronics.

The four-pole ironless winding together with rare earth magnets result in zero cogging, and the combined moulding of the coil, PCB and hall-effect sensors guarantees a reliable, robust construction.

A high torque constant and shallow slope of the speed torque curve ensures consistent delivery of high torques across a wide speed range, while a choice of rotors provides further flexibility.

The addition of a three-channel magnetic encoder within the same outside diameter provides speed and positional feedback in four factory programmable resolutions of 32, 64, 128 and 256 pulses per revolution.

The option of a line driver with differential signal output ensures a stronger signal and maintains integrity even when using long connecting lead wires.

The option of an integrated speed controller makes this combination suitable for the direct replacement of conventional DC motors but with the additional benefits that electronically commutated motors have to offer.

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.
