Product Details Supplier Info More products

Electro Mechanical Systems (EMS) is offering the Faulhaber 3274 BP4 — a four-pole brushless DC servomotor suitable for applications in which high-power and dynamic start/stop operation and low total weight are important.

Faulhaber 3274 BP4

Typical applications include the link drives of humanoid robots, electric grippers used in process automation or high-performance traction drives used in inspection robotics. 

The servomotor measures 32mm in diameter and 74mm in length and has a continuous torque of 165mNm. It weighs in at just under 320g, which is half that of conventional motors with comparable power. The slope of the motor characteristic curve is just 3rpm/mNm with a stall torque of 2.7Nm.

Key features and benefits

  • The 3274 BP4 is overload resistant and operates without wear-prone mechanical commutation.
  • Its operational lifetime is many times longer than that of conventional DC micromotors.
  • The 3274 BP4 can deliver what the application demands even under harsh ambient conditions, such as at low temperatures or high mechanical loads (for example in aerospace applications). This is made possible by a robust stainless steel housing and the omission of adhesives often used for assembly. 
  • The motor offers high flexibility in its design. It is equipped as standard with digital hall sensors.
  • High-resolution optical and magnetic encoders can be attached simply to the rear multifunction flange.
  • As an option, the motor is also available with analogue (linear) hall sensors that can replace an encoder in many application cases.
  • A selection of performance-optimised precision gearheads completes the drive system.

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.
