Product Description:
The 8LSA54.EA045D200-1 from B&R’s 8LS Synchronous Motors series is a top-rated model as its natural convection cooling removes heat without auxiliary components which lowers maintenance requirements. A torque rate of 28 Nm gives heavy-load positioning a good force to keep the positioning correct with high stress. The size of a flange is 130mm that fixes the motor tightly to machine frames that reduces mechanical play.
The gadget with rated speed of 1500 rpm is coupled with a normal servo loop frequency which eases the process of control loop tuning. Internal sealing covers internals against dirt and low-pressure jets and increases uptime, with a protection class of IP65. A rated power of 4.5 kW depicts a lot of energy under constant duty that keeps high-torque unenergized. The standard three‑phase supplies integrate with rated voltage of 400 VAC to prevent the need to have a transformer. The use of patch connector wiring speeds the process of installation and minimizes possible miswiring. EnDat encoder feedback supplies high resolution position information that improves (closes) closed loop accuracy. Such permanent magnet synchronous motor has high efficiency that reduces energy consumption.
A designed current of 10.2 A is a compromise between the sizes of a conductor and the supply of the power that limits the costs of the cabling. Furthermore, the module has a top speed of 6000 rpm that allows quick acceleration cycles making the process shorter. Important drive applications include machine tool spindles for precision machining, electric vehicle traction drives for smooth torque delivery, and wind turbine pitch control for adaptive blade positioning which showcase the motor’s versatility. Other features for 8LSA54.EA045D200-1 include a rotor inertia of 12.3 kg·cm² which enhances stability during speed changes and a peak efficiency of 96.2% which maximizes energy utilization.
Frequently Asked Questions about 8LSA54.EA045D200-1:
Q: Which flange dimension secures the 8LSA54.EA045D200-1 module?
A: A 130 mm flange size anchors the motor rigidly to machine frames. This dimension minimizes mechanical play and ensures stable torque transmission under dynamic loads.
Q: What environmental protection does the 8LSA54.EA045D200-1 have?
A: The unit carries an IP65 rating that blocks dust ingress and withstands low‑pressure water jets. This protection enables reliable operation in washdown and dusty industrial settings.
Q: What voltage amount does the 8LSA54.EA045D200-1 require?
A: It runs on a 400 VAC three‑phase supply to match industrial mains. This requirement avoids external transformers and simplifies electrical design.
Q: Which feedback mechanism integrates with the 8LSA54.EA045D200-1 servo motor?
A: An EnDat encoder provides high‑resolution position and velocity data. This feedback refines closed‑loop accuracy and reduces positioning error in high‑precision tasks.
Q: How much current does the 8LSA54.EA045D200-1 draw under full load?
A: A rated current of 10.2 A balances conductor sizing with power delivery. This current level reduces cabling costs and minimizes heat generation in the motor.
