  • Motor for electric cylinder and encoder for motor
    Patent number: 11791690
    Abstract: A motor for an electric cylinder includes a motor body, an encoder, a rotor coupling portion and an encoder fixing portion. The motor body includes a rotor having a shaft hole through which a rotating shaft extends. The encoder is installed on the motor body and includes a fixing ring fixed on the rotating shaft, a magnet holder combined with the fixing ring, an encoder magnet mounted on the magnet holder, and a magnetic sensor opposite to the encoder magnet. The magnet holder is rotatable relative to the fixing ring to adjust the magnetic pole position of the encoder magnet relative to the magnetic sensor. The rotor coupling portion is arranged on the rotor and fixed to the rotating shaft at a first corresponding position. The encoder fixing portion is arranged on the fixing ring and fixed with the rotating shaft at a second corresponding position.
