Two-phase stepper motor from the Lexium BRS2 series. This motor series is characterized by its robust construction and enables very quiet and almost resonance-free operation. This motor has a holding torque of 4.5 Nm. The flange size is 85 mm. The motor consists of two power levels. The phase current is up to 6 A. Movements are carried out precisely, step by step, which are defined by a Lexium SD2 stepper motor amplifier and are thus perfectly coordinated.
