Product Description:
The LSM75-21-602-S-0KA is a brushless servo motor manufactured by Kollmorgen and operates consistently with power. The motor works precisely and efficiently, making it useful for applications that need to control motion. The motor is often used in automated systems that need to move in a way that is fast and repeatable within strict limits.
The LSM75-21-602-S-0KA servo motor has a peak torque of 8.8 Nm and a constant torque of 2.36 Nm. The motor's maximum speed is 6000 rpm, which lets it move quickly and accurately in industrial automation. The peak stall current is 5.5 A, which keeps the torque steady when the load is static. The motor can handle a high current of 21.6 A and works well with sudden torque needs. The relationship between current and torque power is shown by the torque constant, which is 0.42 Nm per Amp. The back emf that is created during operation is set by the voltage constant of 49 V/kRPM. At 25°C, the winding resistance between phases is 2.26 ohms, which has an impact on both the electrical and thermal performance. The inductance of the windings is 17.9 microhenries from phase to phase, which helps control the current and respond quickly to changes.
The LSM75-21-602-S-0KA servo motor’s mechanical design makes it reliable when it moves in the same way repeatedly. The rotor's moment of inertia is 0.00033 kg-m², which affects how well it speeds up and slows down. The motor weighs 3.1 kg, which makes it good for small spaces with strict weight limits. At the end of the shaft, there is a threaded hole with an M8 x 1.25 mm thread and a depth of 19 mm that makes it possible to securely connect to other parts. The design works for uses that need consistent power and little mechanical backlash.
Frequently Asked Questions about LSM75-21-602-S-0KA:
