    Stepper motor torque constant measurement

    Hi, I have an MST342C02 stepper motor (200 step/rev and 4 phases) with SMD42C2 Driver. I have a converter which gives 48VDC 12.5A from 110VAC. I have Teensy 4.1 as the microcontroller and using Accelstepper library. The motor is connected Bipolar Parallel. Some of the specs are as follows...

    Universal AC motor calculations

    I am currently making a design of AC universal motor (series motor) as a nutrunner (torque wrencher) for bolts wrenching at adjusted known torque. I would like to calculate a load torque using electric parameters such as current, speed. I know that there are an equation of torque T=P/w=IU/w. But...
