Abstract
The subject technology is directed to a motor apparatus or rotary system. In an embodiment, the apparatus includes a housing comprising a first opening positioned on a first side. A motor comprising a shaft is positioned inside the housing. The shaft comprises a first portion extending through the first opening. The apparatus further includes a code wheel and an encoder. The encoder comprises a second opening. The first portion of the shaft extends through the second opening. By extending the shaft through the encoder, the apparatus allows for dual-sided functionality, enabling both ends of the shaft to be used for driving loads or connecting to other components. This configuration enhances space efficiency and the versatility of the motor apparatus, making it ideal for various compact applications.
