### Synchronous motor - Wikipedia

A synchronous electric motor is an AC motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multiphase AC electromagnets on the stator of the motor that create a magnetic field which rotates in time with the oscillations of the line

Because the torque-speed curve is a straight line, it's simple to find the torque that the motor can produce at a given speed, or conversely, to find the motor's speed for a given load (torque) on the shaft. Recall the equation for a straight line: Where: y = value of y axis variable, to be determined . m = slope of the line; change in y divided by change in x. x = value of x axis variable

The Thevenin torque equation was used above to plot the torque-speed curve of an induction machine. Since the torque is given only as a function of slip, it is possible to use that equation to find the slip at which torque is a maximum. However, a mathematically simpler and intuitively clearer answer can be found be considering the power flow in the Thevenin equivalent of Fig. 2. Analysing the

One tool for servo motor selection is the torque-speed curve, which depicts the motor's continuous and intermittent operating zones. Because the servo amplifier can limit the motor's peak speed and torque, it's important to note that torque-speed curves are often based on specific motor and amplifier combinations. Regardless, the continuous and intermittent zones are the ranges of torque

Holding torque is typically higher than running torque, and is limited primarily by the maximum current the motor can withstand. From a practical standpoint, holding torque is the sum of the magnetic force exerted by the coils to hold the motor's current position, plus the detent torque. Once the motor is moving, the torque available at low speeds equals the holding torque minus two times
