4 Key Factors to Consider When Sizing Servo Motors
For example, a servomotor with 4 N·m of RMS torque will experience the same heat rise if it produced 4 N·m of constant torque. Therefore, as long as 4 N·m is in the continuous region of your speed-torque profile, the motor will not overheat. Speed-Torque Curves. Motor speed-torque curves are essential when selecting and sizing servos.

Troubleshooting Induction Motors
approaching zero at zero speed, increasing as the square of the speed up to torque or some lesser required torque at speed. Typical curves are shown in Fig. 3. As a result, successful starting depends on having adequate torque at a point where the load torque becomes significant and approaches the output capability of the motor.
The Torque Equation and the Relationship with DC Motors
The inverse relationship between speed and torque means that an increase in the load (torque) on the motor will cause a decrease in speed. This can be demonstrated by the DC motor torque equation: Where: T = motor torque. V = supply voltage. ω = rotational speed. k = motor constant.

Induction Motor Speed Torque Characteristics.
The curve in Figure 4 shows the actual speed-torque curves which result when a motor is operated from a constant volts-per-Hertz voltage source supply. When low voltage and low frequency is applied to the motor, the maximum torque available decreases at reduced speeds. This is a result of the resistive voltage drop of the stator windings.
What Does the Motor Speed Torque Curve Tell You?
The available motor torque is approximately proportional to the square of the applied voltage. %Torque α %Voltage2. Given this relationship, a 60% reduction in the applied voltage results in approximately an 84% reduction in generated torque. In this example, 40% voltage is used. (0.4)2 = 0.16, or 15% of Locked Rotor Torque is present.

to the rated torque. As discussed earlier, in a BLDC motor, the torque remains constant for a speed range up to the rated speed. The motor can be run up to the maximum speed, which can be up to 150% of the rated speed, but the torque starts dropping. Applications that have frequent starts and stops and frequent reversals of rotation with load ...
