Product Description

The LSM75-21-602-M-OKA is a brushless servo motor in Kollmorgen’s LSM series of servo motors used in setting up drive systems for a variety of applications such as smart conveyors, machinery for packaging, and high duty cycle applications. It accommodates high acceleration and deceleration due to the use of neodymium magnet rotors in its design. Automated temperature sensors in its windings also ensure that in overload conditions, intelligent shutdowns can be triggered to protect the machine. This servo motor can be relied on for efficient operation in unfriendly environments with its highly durable nature and industry-standard parts.

The LSM75-21-602-M-OKA is a 230 Volts servo motor that has a continuous torque of 2.36 Nm and a peak torque of 8.8Nm. It is a 3.1kg device with 8 poles, a stall current of 5.5 amps peak, and a maximum current of 21.6 amps peak. Its rotor speed is 6000 rpm and the moment of inertia of this rotor is 0.000033 kgm².  The torque constant of the servo motor is 0.42 Nm/Amp and its voltage constant is 49 Volts/kRPM. It features a phase to phase winding resistance of 2.26 at 25^o C and a winding inductance of 17.9 mH.

The maximum radial load within which the LSM75-21-602-M-OKA can operate is 24 kg at a 6000 rpm rotor speed. Its shaft is made from steel, and its frame size is 75 frame. It possesses a high-resolution multiturn encoder but has no brakes. Also, it has a keyway and requires an ambient temperature between 0 and 40^o C for optimal operation. When in storage, the LSM75-21-602-M-0KA requires an ambient temperature that ranges from -30 to 70^o C. The non-condensing relative humidity should also be maintained at 5 to 95 %.
