Tight speed regulation for novel servo
design
The Model M815-BR servo drive is a novel unique velocity loop encoder feedback device.
The Model M815-BR PWM servo amplifier accepts input voltages ranging from 20 to 80V DC (unregulated), and features a continuous output current of 8A, with and a peak of 15A for 1s The amplifier accepts a typical input command signal of +/-10V DC, or up to 35V DC maximum

The GM Series of DC planetary gear motors is available in four frame sizes ranging from 1.5 to 4.2in diameter.
Measuring just 5.4 x 1.0 x 3.2in, the Model M815-BR is armed with a number of useful standard features that include adjustable peak and continuous current limiting, a scaleable input command signal, tachometer scaling, and built in diagnostics with protection against overvoltage, overtemperature, and ground faults.
The feature that sets the Model M815-BR apart from all the rest, however, is it's new E-FOB circuit.
This unique design employs Midwest Motion Products' standard encoder feedback onboard circuit, a frequency to analogue voltage convertor that allows the user to employ a DC motor with an optical encoder in a closed loop velocity servosystem.
Very tight speed regulation can be obtained, despite typical torque disturbances, in a velocity-controlled servosystem.
