Abstract
(EN) Disclosed is a dynamo electric machine provided with voids (21) of a prescribed length (1mag) that correspond respectively to supporting units (20), and which are located a prescribed distance (1core) from permanent magnets (17a, 17b) in the flow direction (27) of flux (23), between the permanent magnets (17a, 17b) and a stator (13). The voids are capable of producing magnetic saturation when the electrical supply to a stator coil (24) is in a low current state, and are also capable of not producing magnetic saturation in times of maximum torque when electrical supply is in a high current state. Thus, while providing supporting units (20) with the simple configuration of voids (21), torque decline can be suppressed during a low torque state, decline of maximum torque can be suppressed during a time of maximum torque when in a high current state, and operation efficiency of a dynamo electric machine can be improved.
(FR) L'invention concerne une machine électrique dynamo comportant des vides (21) d'une longueur prédéterminée (1mag) qui correspondent respectivement à des unités de support (20) et qui sont situés à une distance prédéterminée (1core) d'aimants permanents (17a, 17b) dans le sens d'écoulement (27) du flux (23), entre les aimants permanents (17a, 17b) et un stator (13). Les vides sont capables de produire une saturation magnétique lorsque l'alimentation électrique vers une bobine de stator (24) est à un état de courant bas, et sont également capables de ne pas produire de saturation magnétique aux moments de couple maximal lorsque l'alimentation électrique est à un état de courant élevé. Ainsi, tout en utilisant des unités de support (20) avec la configuration simple des vides (21), la diminution de couple peut être supprimée pendant un état de couple bas, la diminution de couple maximal peut être supprimée pendant une période de couple maximal lors d'un état de courant élevé, et l'efficacité de fonctionnement d'une machine électrique dynamo peut être améliorée.
(JA)  各支持部(20)にそれぞれ対応させて、永久磁石(17a,17b)とステータ(13)との間における磁束(23)の流れ方向(27)での永久磁石(17a,17b)から所定距離(lcore)離間した位置に、ステータコイル(24)への給電が低電流状態では磁気飽和を発生させ、かつ給電が高電流状態での最大トルク時には磁気飽和を発生させないようにし得る、所定長さ(lmag)の空隙部(21)を形成した。このため、支持部(20)に空隙部(21)を形成した簡素な構成を備えながらも、低トルク状態でのトルク低下を抑え、高電流状態での最大トルク時には最大トルクの低下を抑えて、回転電機(10)の作動効率を向上させることができる。
