EY Series

The EY Series is a precision DC motor available
as motor only and with most parallel shaft
and inline gearboxes. The EY is an ideal solution
when limited space is available. The EY is
suited for either continuous or intermittent
duty applications. Fitted with available encoder
or tachometer options the EY becomes a very
flexible DC solution.
