Is it possible to detect that a stepper motor is rotating using a Hall sensor against its body? Kind of a simple detection mechanism for motor stall without moving parts.

  • \$\begingroup\$ The stepper motor is a cheap solution, because it doesn't have feedback. It doesn't make sense to add a feedback and cost, since it won't have such performance as BLDC/PMSM for the same price. \$\endgroup\$ – Marko Buršič Dec 6 '20 at 20:35

  • \$\begingroup\$ @PedroNF why the hall sensor? doesn't measuring current give you essentially the same info, but requiring a 2 ct shunt resistor instead of a hall effect sensor? \$\endgroup\$ – Marcus Müller Dec 6 '20 at 20:45
  • \$\begingroup\$ @Markus The motor is controller by a PLC with its stepper controller, just looking for a simple inexpensive external solution, to plug into an input pin of the PLC. \$\endgroup\$ – Pedro NF Dec 6 '20 at 20:47
  • \$\begingroup\$ You'd do better using a hall current sensor on a motor lead \$\endgroup\$ – Chris Stratton Dec 6 '20 at 23:07
