SM86118 stepper motors are widely used in wood and plastic tooling and in working with aluminium alloy materials. The motor can operate in CNC machines, electrical discharge machines, milling systems, grading machines. These motors are successfully used in robotics, laser beam machines and in the rest of automotive industry. SM86118 are good solution for automatic welders and drive executive mechanisms of assembly lines and conveyors. These is just a short list of possible usage examples for SM86118 stepper motors.

To control SM86118 we recommend step motor driver SMD-9.0 or step motor controller SMSD-8.0
