Product Description:
The QSK075C-0300-NN-S5-UG1-NNNN is a powerful synchronous IndraDyn S motor, masterfully crafted by Rexroth Bosch Indramat. Weighing around 16.4 kilograms (about 36.16 pounds), this motor model is suitable for driving various types of loads in both industrial and automation environments. As a relatively small motor, this machine can achieve a higher maximum speed of 5000 rpm but can only reach a maximum torque of 44 Nm. For three-phase machines like motors and generators, the size usually has a positive correlation with the torque capabilities. The shaft speed, on the other hand, mostly depends on the applied supply voltage. Generally, the higher the supply voltage, the greater the speed.
With a 200 VAC supply, the QSK075C-0300-NN-S5-UG1-NNNN can achieve a nominal speed of around 1800 rpm. For a 400 VAC supply, the machine’s shaft can run as fast as 3800 rpm. During normal operating conditions, the machine’s output torque has a fairly linear relationship with the applied input current. At this linear operating region, the torque and input current ratio is equal to 1.58 Nm/A, assuming a stable operating temperature of 20 degrees Celsius. This torque constant implies that the motor’s output torque may increase or decrease by 1.58 Nm for every increase or decrease of the input current, respectively.
During standstill conditions, the QSK075C-0300-NN-S5-UG1-NNNN can achieve a torque and current of 12 Nm and 8.4 A, respectively. The standstill values provide a reasonable estimation of the transient characteristics of the motor, which are essential for designing the machine’s protection system. In total, the QSK075C-0300-NN-S5-UG1-NNNN has four pole pairs, or eight poles, spaced 45 degrees apart. The motor’s casing has a protection category of IP 65 and an insulation class of 155.
