MEASURING MOTOR PARAMETERS - Control Technology …
support.controltechnologycorp.comIf it is a WYE connected BLDC motor, the resistance is the line-to-line resistance. Thus divide the resistance(l-l) by 2 to get the phase resistance. MOTOR VOLTAGE CONSTANT Ke To measure the Ke of the motor, put the motor shaft in a lathe and rotate the shaft at some speed [rpm] such as 1000rpm. With a dc motor, use a dc voltmeter to measure the
Fundamentals of motor control - STMicroelectronics
www.st.com• The motor is controlled applying a voltage on the motor leads. The higher the voltage, the higher the speed. The direction is changed reversing the polarity on the leads. • The maximum torqueis limited by the current rating of the motor and it is obtained at zero speed (start-up).
Speed Control of DC Motors: the speed of a motor is given ...
uotechnology.edu.iqM1 is the main motor whose speed control is required. The field of this motor is permanently connected across the dc supply lines. By applying a variable voltage across its armature, any desired speed can be obtained. This variable voltage is supplied by a motor-generator set which consists of either a dc or an ac motor M2
