Magnomatics provides bespoke design, analysis and manufacturing services for all electrical machine types with particular expertise on high performance machines within challenging operating environments

BRUSHLESS PM MOTORS

Brushless permanent magnet (BLDC/BLAC) machines are widely used in hybrid vehicles, aerospace and industrial drive applications where system volume and mass must be minimised.

Magnomatics personnel have many years experience designing, manufacturing and evaluating brushless permanent magnet machines for applications as diverse as aircraft brake actuators and very high performance machines for Formula 1 Kinetic Energy Recovery Systems (KERS).

SR MOTORS

Switched reluctance (SR) machines benefit from a robust rotor structure without permanent magnets, making this class of machine particularly suitable for very high speed, high temperature applications. They are finding increased usage in the low-cost high-volume automotive sector.

Magnomatics personnel have designed and constructed SR machines for high speed automotive turbo-generators and starter generator systems embedded within civil aircraft gas turbine engines for the more-electric aircraft.

FAULT TOLERANT MOTORS

For many safety-critical applications there is a specific requirement to ensure that a motor or generator will continue to be functional following one or many faults (such as a winding short/open circuit or signal failure). Fault tolerant machines generally require a modification to the rotor/stator coupling and the inclusion of thermally, electromagnetically and physically isolated multiplexed components.

Magnomatics has developed a range of customer focussed fault tolerant machines with inherent anti-jamming features for aerospace flight surface actuators and related electro-hydraulic and lead-screw systems.

HIGH SPEED MOTORS

For many applications there is a requirement to operate the electrical machine at very high speeds, either to couple directly to a high speed component such as an automotive turbine, or provide a more compact, lightweight, power dense system.

The design of very high speed machines requires a multi-physical study of the electromagnetic, mechanical and thermal parameters. All high speed machines are designed with particular regard to engineering concepts that are often neglected in conventional machine design, such as centrifugal rotor stress, rotor critical speeds, enhanced thermal dissipation and aerodynamic losses.

Magnomatics personnel have extensive experience in the design of high speed machines and have published a wide range of papers on the specific design requirements in leading journals.
