ECPA42-2
The ECPA42-2 from B & R Automation is a high-performance module in the ECP Multi Control Modules series, engineered for demanding industrial applications. This NEMA 42 stepper motor offers a precise step angle of 1.8° and an impressive holding torque of 2800 oz-in, ensuring reliable positioning under heavy loads. Driven at a current per phase of 6.0 A, the motor balances power and efficiency for smooth motion control. With a robust shaft diameter of 19 mm and a compact motor length of 132 mm, this module fits seamlessly into a variety of mechanical assemblies. The unit’s weight of 7.4 kg underscores its solid construction, optimized for stability and longevity in industrial environments.
Technical performance is enhanced by a low resistance per phase of 0.34 Ω paired with an inductance per phase of 6.5 mH, delivering responsive current regulation and minimal heat buildup. The motor’s rotor inertia of 2700 g-cm² supports rapid acceleration and deceleration cycles, while a detent torque of 14.5 oz-in prevents unintended drift when stationary. Its insulation class B (130 °C) rating ensures reliable operation at elevated temperatures, and the number of leads (8) provides wiring flexibility for bipolar or unipolar configurations. With a design optimized for energy conversion and control dynamics, this stepper motor maintains crisp step response under varying loads.
Operational reliability is assured across a wide operating temperature range of –20 °C to +50 °C, making it suitable for harsh factory settings. The motor’s maximum radial load capacity of 220 N enhances shaft support in belt-drive or gear-reduction systems, minimizing wear and extending service life. Its inherent precision and high torque output reduce vibration and resonance, providing stable motion in CNC machining, pick-and-place, and inspection equipment. The combination of rugged mechanical design and finely tuned electromagnetic characteristics allows for consistent performance under continuous duty.
Integration into complex automation systems is simplified by the module’s compatibility with standard NEMA 42 mounting dimensions and multi-lead wiring options. Its robust construction and professional grade specifications make it ideal for robotics, automated assembly lines, and motion control platforms. Engineers can leverage the ECPA42-2’s precise step accuracy and high holding torque to achieve tight positional tolerances and reliable clamping functions. With seamless interoperability in industrial automation environments, this stepper motor elevates system performance and uptime.
