The IR compensation<\/strong> method is used to provide the speed regulation in our DC motor speed controls. When the load of a PMDC motor increases, the amount of current that the motor draws also increases. Per the performance characteristics of permanent magnet DC (PMDC) motors, an increase in load will cause a decrease in speed, because of the negative correlation between speed and torque (see speed-torque curve below).<\/p>\n

\"\"<\/a><\/p>\n

IR compensation increases the voltage going to the motor, thus compensating for changes in the load, in order to maintain a constant speed at the end-user\u2019s setting. As a reminder: In a PMDC motor, speed is proportional to the applied voltage, torque is proportional to the available current.<\/p>\n
