Brushless motors provide precise speed control

An EMS product story
Edited by the Engineeringtalk editorial team Feb 11, 2008

The Smartshell is a cost-effective solution suitable for demanding drive applications where precise speed control is required.

EMS has released the Smartshell brushless motor series from Minimotor.

The Smartshell is a conventional brushless DC-servomotor based around the Faulhaber self-supporting skew wound coil.

The coil, PCB, laminated stack and front-end cover are all encapsulated together in an injection moulded LCP (liquid crystal polymer), giving outstanding mechanical and thermal features.

The Neodymium rare earth magnet provides superior dynamic performance.

The monolithic design ensures a simple compact and very robust stator is guaranteed.

The anodised aluminium front and rear motor covers provide the optimum location for pre-loaded ball bearings, a secure mounting fixture in the application and ensure excellent heat dissipation.

The modular construction gives this motor real versatility.

The entry-level motor is sensorless, resulting in a cost-effective solution suitable for demanding drive applications where precise speed control is required.

If more sophisticated motion control is required then the motors can be equipped with a hall sensor module with either digital or analogue sensors.

The series is available from 15-22mm with a power range up to 31W.

The low rotor inertia and impressive acceleration delivers speeds up to 62,000rev/min, a truly dynamic performance with exceptional long life.

Complementary drive electronics and the comprehensive range of minimotor gearheads, enables optimisation of the drive to meet the most demanding applications.
