TEMPERATURE EFFECTS ON MOTOR PERFORMANCE

2017-11-15· Gold Copper Aluminum speed-torque curve will result in a smaller change in shaft speed with increased load. As the motor tempera-ture increases and the curve becomes steeper, shaft speed will drop more for the same increase in load. TEMPERATURE EFFECTS ON MOTOR PERFORMANCE, K K.,))

What is the relation between the stator current and motor

2020-04-11· The motor speed depends on the motor's speed-torque curve vs. the fan's speed-torque curve. The fan's speed-torque curve depends on the inlet air density. The speed of the air exiting the fan presumably depends on mechanical details such as the pressure drop in the fan's duct work, the open/closed position of air dampers, and so on.

Understanding DC Motor Curves and Temperature

At an elevated motor temperature, the slope of the DC motor curve increases as a result of an increase in no-load speed and a decrease in locked rotor torque (sometimes referred to as stall torque). Figure 3 illustrates the total area beneath a particular motor curve that can be considered the range of consistent performance between room temperature and maximum rated motor

Alternator Technology Page: Torque and Power Curves,

2019-04-08· An advantage of the higher speed requirement to produce power plus the higher number of poles for an alternator motor is that simple 6-step ("trapezoidal") inverter drives can often be used instead of more complicated Space Vector sinusoidal drives because the high speed plus large number of poles of an alternator motor tends to "naturally" smooth out torque, tending to have less torque ripple.
