Product Description:
The 8Lsa66.Eb045d200-3 Synchronous Motor from B & R Automation a global provider of innovative automation and control technology, is designed for accurate and effective control in challenging engineering systems. This motor features a self-cooling mechanism that maintains temperature without external cooling units. The motor belongs to the size 6 category and offers an extra-large motor length for high-power and continuous-duty tasks.
The 8Lsa66.Eb045d200-3 Synchronous Motor delivers a rated torque of 12 Nm which supports high-load applications efficiently. The rated speed is 4500 min^-1 with a maximum speed reaching 6000 min^-1. Its rated power output is 5.65 kW which enables strong and reliable operation. A current of 10.91 A supports this performance level. The torque constant is 1.1 Nm/A and the voltage constant is 65.97V/1000 min^-1 for stable output under varying conditions. The motor comes with a smooth shaft end suitable for precise connection setups. The electrical time constant is 10.57 ms derived from the stator resistance of 0.25 ohms and stator inductance of 2.59 mH. This combination allows for responsive and controlled motor behavior. The motor includes a normal holding brake aiding in safe system shutdowns. It has no oil seal which makes it suitable for dry environments.
The 8Lsa66.Eb045d200-3 Synchronous Motor has a connection direction that is angled with a swivel connector, simplifying cable arrangements. The motor's moment of inertia with the brake is 5.85 kg.cm^2 which enables balanced acceleration and deceleration. This makes the 8LS Synchronous Motors ideal for automation systems that demand performance and control. This product offers a complete solution for synchronized motion in industrial settings.
Frequently Asked Questions about 8Lsa66.Eb045d200-3:
Q: Why does the 8Lsa66.Eb045d200-3 motor use a smooth shaft end?
A: The smooth shaft end minimizes mechanical misalignment during coupling. It ensures lower vibration transmission in precision-driven systems.
Q: What advantage does the 10.57 ms electrical time constant provide in this motor?
A: The short electrical time constant allows the 8Lsa66.Eb045d200-3 motor to respond quickly to dynamic control signals. This is crucial for fast-changing automation commands.
Q: How does the 5.85 kg.cm^2 moment of inertia with brake benefit the 8Lsa66.Eb045d200-3 motor?
A: The increased moment of inertia aids in smoother acceleration and deceleration phases. This improves control accuracy during rapid speed changes.
Q: Why is the absence of an oil seal important for the 8Lsa66.Eb045d200-3 motor?
A: The lack of an oil seal makes it suitable for dry and clean environments. It also reduces maintenance needs in dust-free applications.
Q: How does the 0.25-ohm stator resistance impact motor efficiency?
A: The low stator resistance in the 8Lsa66.Eb045d200-3 helps reduce copper losses. This improves overall thermal performance during continuous-duty operation.
