Performance characteristics such as power output versus wind speed or versus rotor angular velocity must be optimized in order to compete with other energy sources. Yearly energy production and its variation with annual wind statistics must be well known. The shaft torque must beABB DRIVES AND CONTROL SYSTEM FOR HOT FLAT ROLLING,The speed reference at threading can be between 30 – 50 % of nominal speed. At those speeds the power factor of the cycloconverter is really bad, maybe cos ϕ=0,3. When the slab enters into the rolling mill the actual speed of the work rolls drops, because the speed controller needs time to build up the torque reference.Building a DC Drive for the Bridgeport Spindle,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.

Step Two (plot current vs. torque and speed vs torque) Prepare a graph with motor torque on the horizontal axis, motor speed on the left vertical axis, and motor current on the right vertical axis. Scale the axes based on the measurements in step 1. Draw a straight line fromDC Motors - University of Minnesota,Torque-Current Curve. For DC motors, the output torque is proportional to the current going into the motor no matter what the motor speed. The straight-line relation between torque and current is the torque-current curve as shown below.,
