8MSA3M.E1-42
The 8MSA3M.E1-42 is a high-performance synchronous motor developed by B & R Automation within the 8MS Three Phase Synchronous Motors series. It features a compact diameter of 42 mm and a precise bore size of 8 mm, making it well-suited for space-constrained installations. Constructed from durable aluminum alloy with an anodized surface treatment, this unit weighs just 0.12 kg and includes a robust flange for secure mounting. The pitch of 3 mm and number of teeth: 14 ensure reliable engagement in timing applications. Designed for industrial environments, it operates effectively within a temperature range of -20°C to +80°C.
Technical excellence is at the core of the 8MSA3M.E1-42’s capabilities. The motor delivers a continuous mechanical power output of 0.63 kW and a rated torque of 1.00 Nm, while reaching a maximum speed of 12000 min⁻¹. Its electrical dynamics are characterized by an electrical time constant of 1.69 ms, stator winding resistance of 12.7 Ω, and phase inductance of 21.5 MHz, ensuring rapid response and tight control. A torque constant of 0.78 Nm/A optimizes current-to-torque conversion, while a peak current capacity of 5.2 A and standstill current of 1.67 A provide the headroom necessary for dynamic load changes.
Operational reliability is enhanced by multiple built-in features. The synchronized braking system can hold up to 2.25 Nm when engaged, preventing unwanted motion during power loss. A starting torque of 1.3 Nm guarantees confident acceleration under load, and the moment of inertia of 0.18 kg·cm² balances responsiveness with stability. Recommended wiring uses 1.5 mm² conductors to safely carry current without excess heating or voltage drop. Classified as a Timing Pulley, this motor integrates seamlessly into belt-driven systems with minimal backlash and wear.
Integration into automation platforms is straightforward. It is optimized for the 1016 servo drive, enabling advanced control modes and plug-and-play commissioning. The combination of aluminum alloy construction, anodized surface treatment, and a pre-configured 14-tooth pulley interface makes it ideal for applications in packaging machinery, conveyor systems, and precision indexing tables. Engineers will appreciate its compact footprint, robust mounting flange, and broad operating temperature tolerance for demanding industrial automation environments.
