Product Description:
The 8MSE8L.E1-P12C Three Phase Synchronous Motor is a high-performance unit from B & R Automation a company known for its advanced industrial automation solutions. The 8MS Three Phase Synchronous Motors are designed for demanding motion applications requiring high precision and durability. It features a rated voltage of 350 VAC across three phases which make it suitable for robust power delivery.
The 8MSE8L.E1-P12C 3 Phase Synchronous Motor delivers a rated speed of 2000 RPM for efficient performance in continuous duty operations. It provides a rated torque of 91 Nm and a stall torque of 120.9 Nm which offers strong operational stability under varying loads. This motor integrates an EnDat multi-turn encoder system. It uses EQN1325 with 512 lines and supports 4096 revolutions for accurate position feedback and multi-turn counting. The input current is 33.80 A during standard operation. During stall conditions, the motor requires 43.03 A which confirms its capability to handle high load starts. The motor has an isolation class of F for insulation reliability at elevated temperatures. It comes with an IP64 protection class which provides protection against dust ingress and water splashes from any direction. The cooling method is natural cooling for heat dissipation without forced ventilation. This simplifies installation and maintenance in enclosed setups. The mounting style is flange which allows secure and stable integration in mechanical assemblies.
The 8MSE8L.E1-P12C 3 Phase Synchronous Motor has a power connector is positioned at the back side of the motor and faces upward for efficient cable management. The unit performs reliably in ambient temperatures ranging from 0 to +40 degrees Celsius. It supports a humidity range of up to 80%, non-condensing which allows use in humid environments. The allowed installation height is up to 1000 MSL for consistent output across various elevations.
Frequently Asked Questions about 8MSE8L.E1-P12C:
Q: Why does the 8MSE8L.E1-P12C use a multi-turn EnDat encoder system?
A: The multi-turn EnDat encoder ensures accurate absolute position tracking over multiple revolutions, improving feedback integrity in applications requiring long-term synchronization or homing-free operations.
Q: How does the EQN1325 encoder with 512 lines enhance control performance?
A: The 512-line resolution allows for fine-grained motion detection, significantly improving the motor's closed-loop accuracy during high-speed or high-torque conditions.
Q: What is the importance of the 43.03 A stall current capacity in the 8MSE8L.E1-P12C?
A: The stall current capacity ensures strong torque delivery at startup, critical for initiating motion in systems under static load or high inertia.
Q: How does 350 VAC supply voltage contribute to motor performance?
A: The 350 VAC three-phase input supports high torque output while minimizing current draw per phase, enhancing energy efficiency under dynamic loads.
Q: Why is the upward-facing rear power connector useful in the 8MSE8L.E1-P12C?
A: The upward rear connector orientation simplifies cable routing in vertical panel setups, reducing bending stress on wires and improving installation accessibility.
