Product Description:
The 8LSA44.R0045D200-0 synchronous motor can operate at speeds of up to 6000 rpm and has a rated torque of 4.5 Nm. It also features a design that keeps it cool. This is one of B & R Automation's 8LS Synchronous Motors. It includes IP65 protection to make sure it works reliably. That being said, the 8LSA44.R0045D200-0 is well protected against dust, vapor, and gas. Rated Torque which is an important characteristic sits at "4.5 Nm" for this motor. As a result, this motor is able to achieve required torque and speed when necessary. The 8LS series offers a tri-phase, permanently excited, electronically commutated synchronous motor that is perfect for applications that need rapid dynamic reaction and great positioning precision. Designers also like how light and small the series is. An NdFeB permanent-magnet rotor creates a high-density field that gives a lot of torque in a remarkably small space. Neodymium-Iron-Boron is one of the strongest commercial magnet alloys, therefore even a regular ceramic-backed pole shoe may feel quite powerful in the technician's palm. The same field that holds the rotor down also quickly snaps it back to the center, getting rid of the lag that smaller motors sometimes have. Sinusoidal commutation, on the other hand, needs smooth three-phase waveforms instead of the harsher square pulses that cheaper drives provide. An EnDat absolute encoder gives a digital position reading that is suitable for more than a million counts per rotation. The resolver option is best for field deployment locations that need to be able to handle temperature and stress. Both devices let the control loop change the current phasing many hundred times a second. This is something that most machine tools need to do if they want to complete work without noise throughout the shift.
Frequently Asked Questions about 8LSA44.R0045D200-0:
Q: What is the main benefit of the "Absolute Encoder" on this motor?
A: Can this motor achieve its "Max Speed" of 6000 rpm while maintaining "Rated Torque" of 4.5 Nm?
Q: No, torque typically decreases beyond rated speed into the field-weakening region.
A: What power source is required for the 8LSA44.R0045D200-0?
Q: It requires a 400V AC power supply (or compatible drive) capable of 2.1 A.
A: Is this motor suitable for applications needing both high speed and precision?
Q: Yes, its high max speed and absolute encoder make it ideal for such tasks.
A: What kind of loads can this motor effectively drive with 4.5 Nm "Rated Torque"?
Q: It is suitable for small to medium-sized applications requiring moderate torque and dynamic response.
A: Yes, it is.
