The basic idea of the project (run in collaboration with a Swiss company) is to design a flexible winding, which will 'replace' the classical slotless BLDC motor winding. The new winding should be thermally and mechanically improved compared to the classic ...
Stepper motors are a very convenient and economical solution for accurate positioning applications where long lifetime and low wear are required. Their particularly simple open-loop operation reduces the number of control components to a minimum. However, ...
Electrical machines consumed the amount of 9’346 TWh in 2019, corresponding to more than 40% of the total global electricity consumption. With the growing demand for automation of production lines and electrification of the transport industry, this value i ...
This research work has been triggered by an industrial project aimed at modelling and manufacturing a small-scale very high speed motor. Very high speed electrical motors offer the main advantage of reducing the size of a system. Indeed, at constant output ...
The induction motor offers the best value for money and is therefore used in many different application fields where power requirements are higher than a few kilowatts. ln order to be able to reduce the priee and the motor's size, a control algorithm based ...
The intrinsic characteristic of a permanent magnet synchronous motor is defined by its internal dimensions, its material properties, as well as the power supply used in conjunction with the motor. When an extended operating range is desired but the electro ...
Energy saving becomes more and more important. Therefore different improvements have been made in motor design, electronic devices and software in order to increase the overall efficiency of electronic motor drives. Permanent Magnet Synchronous Motors (PMS ...
Slotless windings are commonly used in small size high-speed electrical brushless dc machines. Unlike slotted windings, forced to follow the direction of slots, slotless windings can be freely arranged in the airgap. This represents several opportunities f ...
Slotless windings are commonly used in small size high-speed electrical brushless DC machines. Unlike slotted windings, forced to follow slots direction, slotless windings can be freely arranged in the airgap. This represents several opportunities for opti ...
This work studies the level-set based topology optimization for the optimal layout of winding in electric motor. The functional to optimize is to maximize the torque in the air-gap. The coil domain is initiated by a level set function. The time evolutionar ...
