Details

Tittle:
The reaction motor with outer rotor
Summary:
An institute from Latvia involved in electrical engineering, and more specifically - electrical machinery has developed a reaction motor with outer rotor, that has simplified, enhanced security and a specific torque design as well as decreased vibration level. Technology can be applied to low-power electric drive, such as handheld power tools. Institute is looking for commercial agreement with technical assistance.
Description:
Usually for low power electrical drive synchronous motor with reactive segmented rotor is used, which, thanks to a reduced transverse flow direction, has a high overload capacity. This arrangement has drawbacks related to longitudinal magnetic flux reduction due to magnetic resistance increase in the longitudinal direction as well as low rotor mechanical strength and high labor intensity of manufacture.
An institute from Latvia involved in electrical engineering has developed a motor that works as follows: when voltage is applied to the stator winding, a rotating magnetic field arises, whose longitudinal and transversal components in the interaction with currents in the stator winding create a torque. Owing to a significant reduction in the transversal component of the magnetic field, the specific torque in the proposed design considerably increases. The simplicity of the design ensures high reliability of the motor. The distributed winding with a shortened pitch as well as the pole overlapping coefficient and bevelling of stator slots reduce the vibration level of the electric machine.
Institute is looking for commercial agreement with technical assistance in order to offer the technology for acquisition by the result of international cooperation.
Advantages and Innovations:
Properly selecting the engine structural elements: a minimum number of poles, non-magnetic gaps between the teeth, as well as the width and pole multiphase stator windings, it is possible to significantly reduce the flow of cross-axis direction, and thereby increase the specific moment, as well as to create a secure electrical machinery construction.
Pole coverage ratio selection, divided winding, winding steps and the reduction of oblique grooves approximates the distribution of magnetic flux density in air gap to sinusoidal. This reduces the magnetic field and the electromagnetic torque higher harmonics and vibration and noise of electrical machinery are eliminated.
