美国BEI HS22系列增量型编码器说明
The HS22 series of hollow shaft incremental encoder offers application advantages
over conventional optical encoders. This heavy duty unit is designed for
ease of installation to a servo motor, the encoder’s flexible coupling fits over the
driven motor shaft to provide an accurate, backlash-free method of attachment.
The mounting method eliminates the need for couplings, sprockets, or gearing.
The integral flex mount provides for a 20-degree angular adjustment. Throughshaft
or blind shaft configurations of the HS22 encoder are available.
Through-shaft units allow for applications where the center of the encoder must
be used for transmission of fluids, cabling, or optics. Blind shaft units are designed
to mate with shaft lengths of 0.50 to 1.50 inch. Standard outputs for both configurations
incude: A and B in quadrature with index and optional commutation signals for
brushless motor control.
