- What's the efficiency of a gearhead in case of blocking?
In case of a blocking gearhead, the total motor torque Mmot multiplied with the reduction ratio i is effective at the gearhead output (torque ML). Basically, static leverage equations apply to the situation. There is no friction and hence, the efficiency η seems to be 100%.
ML = Mmot * i * η = Mmot * i * 1
