ST4209 high torque stepper motor - Nema 17
In addition to their compact size (41x41mm), motors of the ST4209 series offer a very high torque and a double so fine resolution of 400 steps/revolution. This enables smooth operation with maximum precision.
In conjunction with microstep drives of the IMT series and the stepper motors controls of the SMCI series, these motors present an extremely favorable alternative to multiphase stepper motors.
