Title
(EN) ELECTRONICALLY COMMUTATED MOTOR AND CONTROL SYSTEM
(FR) MOTEUR À COMMUTATION ÉLECTRONIQUE ET SYSTÈME DE COMMANDE
Abstract
(EN)
A power tool having an electronically commutated DC motor capable of providing various operating modes ranging from a maximum efficiency operating mode to a maximum power operating mode. The motor has a rotor having permanent magnets mounted in recesses in a back iron of the rotor. In one embodiment the motor has three phase windings, each having at least a pair of coils. The phase windings are connected in either a delta or a wye configuration via electromechancial or electronic switching components, or a combination of both, by a controller within the tool. The coils in each phase winding can also be switched between series and parallel configurations to configure the motor to provide its various operating modes. In one embodiment a dual wound moto is disclosed that has its phase coils dynamically or statically switchable between series and parallel configurations.

La présente invention concerne un outil électrique doté d'un moteur à commutation électronique fonctionnant sur courant continu proposant divers modes de fonctionnement allant d'un mode « efficacité maximale » à un mode « pleine puissance ». Le moteur comporte un rotor doté d'aimants permanents installés dans les renfoncements d'un métal d'encadrement du rotor. Dans un mode de réalisation, le moteur a trois enroulements de phase, chacun ayant au moins une paire de bobines. Les enroulements de phase sont raccordés en configuration Δ ou Y par des composants de commutation électromécaniques et/ou électroniques, par une commande dans l'outil. Les bobines dans chaque enroulement de phase peuvent aussi être commutées entre des configurations série et parallèle pour configurer le moteur suivant ses divers modes de fonctionnement. Un mode de réalisation concerne un moteur à enroulement double dont les bobines de phase peuvent être commutées dynamiquement ou statiquement entre des configurations série ou parallèle.
