FrankLi Posted November 27, 2005 Report Share Posted November 27, 2005 Dear all: Could you help me to understand how robicon drive gets the motor torque current? Some VFDs will only show motor current. Is it a calculated number? Thanks and best regards Frank Link to comment Share on other sites More sharing options...
marke Posted December 5, 2005 Report Share Posted December 5, 2005 Hello Frank Welcome to the forumAs a major part of modern variable speed drives revloves around a mathematical motor model, the torque current can be calculated using the resistive component of the current flow with an alowance for the losses in the motor.
