The Arcus TM 80 is a stepper motor designed for precision control applications, characterized by its NEMA 17 size designation. It operates as a 2-phase bipolar stepper motor and provides high-resolution positioning due to its encoded feedback. With a basic step angle of 1.8°, it boasts a positional accuracy of ±0.09° when unloaded. The TM 80 is available in two stack configurations, the double stack (TM-STPP-17-2-R2500) and the triple stack (TM-STPP-17-3-R2500), offering different torque ratings. The rated current for both models is 1.2A, with the double stack having a rated resistance of 3.2 Ω and the triple stack at 4.1 Ω. Inductance levels are measured at 8.7mH for the double stack and 10.8mH for the triple stack. The holding torque is rated at 0.48N·m for the double stack and 0.72N·m for the triple stack, accommodating a wide range of applications from 3D printers to robotics. The motors support an operational ambient temperature range of 0°C to +50°C and a storage temperature range of -20°C to +70°C while maintaining high performance in varying humidity levels. Each motor is designed to endure at least 5000 hours of operation under ideal conditions, making them reliable components.
