The invention discloses a centrally-mounted motor applying a rotary transformer and an electric bicycle, and provides two technical schemes for the centrally-mounted motor, each technical scheme adopts a three-shell and two-cavity structural design, a motor mounting cavity and a rotary transformer mounting cavity which are located on the two sides of a transition shell are constructed, and a motor assembly is arranged in the motor mounting cavity; and the rotary transformer is arranged in the rotary transformer mounting cavity. According to the centrally-mounted motor provided by the invention, the rotary transformer is mounted at the non-power output end of the rotating shaft, and the motor mounting cavity and the rotary transformer mounting cavity which are independent of the transmission cavity in the motor shell are formed through butt joint of the main machine shell, the transition shell and the motor cover, so that assembly of the motor assembly, the rotating shaft and the rotary transformer is facilitated; and the motor mounting cavity and the rotary transformer mounting cavity are isolated from each other through the transition shell, so that the rotary transformer and the motor assembly can be isolated, and electromagnetic interference between the rotary transformer and the motor assembly in the rotating process is prevented.

    本发明公开一种应用旋转变压器的中置电机及电动自行车,针对中置电机提供了两个技术方案,均采用三壳两腔的结构设计,构造出位于过渡壳体两侧的电机安装腔和旋变安装腔,将电机组件设置在电机安装腔中,将旋转变压器设置在旋变安装腔中。本发明提供的中置电机,将旋转变压器安装在转轴的非动力输出端,通过主机壳、过渡壳体、电机盖三者对接形成了独立于电机壳内部传动腔的电机安装腔和旋变安装腔,从而便于电机组件、转轴和旋转变压器的装配,并且通过过渡壳体将电机安装腔和旋变安装腔相互隔离,从而能够将旋转变压器和电机组件进行隔离,防止二者之间在转动的过程中电磁干扰。
