Building a DC Drive for the Bridgeport Spindle - truetex

February, 2004 -- August, 2011. The primary power in a vertical milling machine is an electric motor driving the spindle. In this project, I replaced the original 1-HP 3-phase 230 VAC electric spindle motor on a Bridgeport machine with a 3/4-HP DC drive motor.

Gear unit. In wind turbines, there is a "conflict of interests" between the rotor's drive speed, limited, for example, by pitch speed, and the required rotational speed of the generator.With two pole pairs, a rotational speed of 1500 rpm is required for a mains frequency of 50 Hz. [4]. The solution is to use a gear unit. Gear units convert rotational speed and torque and transmit high power.

• For a given wind speed, rotor efficiency is a function of the rate at which the rotor turns. A common way to illustrate rotor efficiency is to present it as a function of the tip-speed-ratio: where rpm is the rotor speed, D is the rotor diameter (m); and v is the wind speed (m/s) upwind of the turbine.
