How do I install a rotary encoder with a variable frequency motor?！

A: The installation of rotary encoders, the situation may encounter the following:
    1. And frequency motor with
    The frequency conversion motor has already considered the question which installs the encoder, its extension shaft is longer, only needs to select the axle diameter to be quite the sleeve type type encoder then.
    2. The encoder is mounted at the rear of the motor without an output shaft
    When there is no output shaft at the rear of the motor, a hole can be opened in the rear end cap and a shaft with a shaft diameter matching the encoder can be mounted on the rear shaft, as shown in Figure 3-35 (a) Section. The fixed part of the encoder can be secured to the end cap of the motor by means of an S-shaped steel sheet, as shown in the black part of the figure.
    This method is also suitable for installation where the shaft diameter of the motor does not match the bore of the bushing type encoders.
    3. Installation of shaft type encoders
    When installing the shaft type encoder, a coupler can be added. The two sides of the coupling are connected to the axis of the motor and the shaft of the encoder, respectively, as shown in the gray section of Figure 3-35 (b). The shaft diameters on both sides may or may not be the same. The fixed part of the encoder can be fixed to the end cover of the motor by the mounting bracket, as shown in the black part of the figure.
