Miniature motors suit all applications

For applications as diverse as medical equipment and robotics, security devices and instrumentation, EMS is now offering the extensive FTB range of high-performance low-profile miniature motors. The motors are available in direct drive versions with torque ratings from 0.05 to 3mNm, and in geared versions with ratings from 50 to 180mNm. All the new motors feature ironless rotors with three flat oval copper coils, which rotate in an axially oriented magnetic field, and which have very small moments of inertia.

This design allows high rates of acceleration to be achieved with minimal flutter, and provides complete freedom from cogging.

In addition, the linear characteristics of the motor make it easy to provide accurate speed control.

The low-profile construction of the motors, which vary in thickness from 5.2 to 8.2mm for direct drive types, and from 12 to 19.1mm for types with gearboxes, makes them an ideal choice for use in modern equipment, where minimum overall size is almost always a prime requirement.

All the motors in the range are available in versions to suit 3 and 6V supplies, with many models available to suit other voltages from 2 to 24V.

Recommend maximum operating speeds for direct drive motors are between 5500 and 10,000rev/min, depending on the motor size.

In addition to FTB motors with integral gearing, EMS also offers compatible spur gearheads for many of the motors in the range.
