    • The invention relates to a portable power tool (10), in particular an angle grinder, having at least one electromotive drive (18), in particular an electronically commutated motor (20), that acts on a drive shaft (30), said electronically commutated motor (20) being intended to drive a tool spindle (22). A first housing (12) consisting of at least one first housing half shell (13) has at least one first housing part (14) which accommodates the electromotive drive (18), and a second housing part (16) which acts as a handle (24). A rechargeable battery (26) acts as power source. It is proposed that a ratio of a diameter (d
      1 ) of the electromotive drive (18) to a diameter (d
      2 ) of the second housing part (16) is between 0.6 and 1.1, preferably between 0.7 and 0.8.
    • 便携式电动工具,特别是角磨机,包括至少一个电动驱动器,第一壳体和可充电电池。 电动驱动器,特别是电子换向马达,作用在驱动轴上,并被配置成驱动工具主轴。 第一壳体具有至少一个第一壳体半壳体,构造成接收电动驱动器的至少一个第一壳体部件和形成手柄的第二壳体部件。 电池被配置为便携式电动工具的电源。 电动驱动器的直径与第二壳体部件的直径的比率在0.6和1.1之间,优选在0.7和0.8之间。
