Prior to the advent of the adjustable-speed drive (ASD), the polyphase induction motor operated as a constant-speed motor. Figure 1 shows the well-known torque and current curves versus speed for the ...
Servomotors and stepmotors are candidates for incremental control applications. Engineers should consider both types and determine which gives the best competitive edge for a given machine. Often, the ...
Electrical equipment often has at least one motor used to rotate or displace an object from its initial position. There are a variety of motor types available in the market, including induction motors ...
