80MPH3.300S000-01
The B & R Automation 80MPH3.300S000-01 is a high-performance member of the 80M Stepper Motors series, engineered for demanding industrial automation applications. This three-phase asynchronous electric motor features a frame size of 80 and delivers a rated power of 0.75 kW at a rated speed of 2840 rpm, conforming to Efficiency Class IE3 for optimal energy utilization. Encased in a robust IP55 enclosure protection shell, it resists dust ingress and moderate water jets, making it suitable for harsh factory environments. Designed for continuous operation, the motor supports Duty Type S1 (Continuous duty) and self-ventilated Cooling Type IC411 to ensure stable thermal performance under sustained loads. With a nominal rated voltage of 230/400 V at 50 Hz, it integrates seamlessly into global electrical systems and supports both star and delta wiring configurations.
Performance is characterized by a precise stepping angle of 1.8°, a holding torque of 7.8 Nm, and a stall torque of 5.5 Nm, delivering accurate incremental positioning with high torque density. Electrical parameters include a phase resistance of 2.2 Ω and inductance of 17.3 mH in serial wiring at 3 A phase current, which can be paralleled to 0.6 Ω, 4.3 mH, and 6 A for higher-speed response. The motor’s number of poles (2) and rotor inertia of 2.61 kg·cm² yield rapid dynamic response, while the detent torque below 210 mNm ensures smooth step transitions. Mechanically, it supports a maximum radial load of 290 N and axial load up to 225 N, with a keyed shaft for reliable coupling. The integrated 300 mm, 22 AWG UL 3266-rated cable simplifies installation and maintains signal integrity.
Reliability is evidenced by an average time between failures of 20,000 hours, underlining its suitability for continuous industrial duty. The compact 98 mm length and lightweight design (3.0 kg) facilitate easy integration into multi-axis gantries, robotics, and conveyor systems. Mounting in a B3 foot-mounted orientation offers flexibility for baseplate or bracket installation, while the IP55 housing extends operational endurance in dusty or moisture-exposed settings. Dual wiring options enhance compatibility with a variety of stepper drives and controllers, promoting plug-and-play integration. Ideal for precision motion control in semiconductor handling, packaging machinery, and automated assembly, the 80MPH3.300S000-01 delivers dependable performance where accuracy and uptime are critical.
