Product Description:

The KDA 3.2-050-3-D0S-W1 AC main spindle drive delivers 50A at 300V. A heat sink fan is utilized in the forced cooling system to ensure proper operation. The drive has a strong design that allows for easy integration into spindle drive systems. The Indramat AC Main Spindle Drive is designed for precision control of the automation industries.

The KDA 3.2-050-3-D0S-W1 AC main spindle drive is 525 mm high and 390 mm wide. The width of the drive is 355 mm. The KDA spindle drive weighs 5.9 kg, and the fixing parts add another 1.7 kg to the weight. The spindle drive fan measures 110 mm tall, but with protection, it may be enlarged to 125 mm. The main spindle drive requires 4.2 kg to move the blower. The blower of the drive is 88 mm deep. The KDA spindle drive has a width of 169 mm. The drive fan for the heat sink requires 220V at 50-60 Hz to operate. The lengths between the mounting holes are 160 mm up and down and 345 mm across. The drive features a digital 16-bit parallel speed setpoint. It has an RS-232C serial interface but no additional encoder inputs.

The KDA 3.2-050-3-D0S-W1 AC main spindle drive's built-in heat sink fan effectively cools the device. The air vent is 25 millimeters deep. Without the air duct, the fan measures 160 mm long. The KDA spindle drive is 185 mm in length when including the air duct. The air vent is 185 millimeters wide. The form of the mounting holes makes installation safe and supports stable operation. The digital interface allows users to precisely control the speed, which makes the spindle drive work better.
