| 发明名称 | Embedded encoder for an outrunner brushless motor | ||
| 摘要 | An example embedded encoder for an outrunner brushless motor is provided. An example motor includes a motor shaft, a stationary stator, a rotor coupled to the motor shaft and provided external to the stationary stator for rotating around the stationary stator to cause rotation of the motor shaft, and a faceplate coupled to the stationary stator that includes a cavity. The motor also includes an encoder embedded into the cavity of the faceplate that comprises a code wheel coupled to the motor shaft and a read head for providing an output indicative of an angular position of the code wheel. The faceplate provides alignment between the code wheel and the read head. | ||

| 主权项 | 1. An outrunner brushless motor comprising: a motor shaft; a stationary stator; a rotor coupled to the motor shaft and provided external to the stationary stator for rotating around the stationary stator to cause rotation of the motor shaft; a faceplate coupled to the stationary stator, wherein the faceplate includes a cavity, and the faceplate abuts and is connected to a chassis; and an encoder embedded into the cavity of the faceplate, wherein the encoder comprises a code wheel coupled to the motor shaft and rotates due to rotation of the motor shaft and a read head attached to the faceplate for providing an output indicative of an angular position of the code wheel, wherein the faceplate provides alignment between the code wheel and the read head. | ||
