Product Description:
This model KDA 2.1‑100‑3‑DYI‑W1 is a high-performance spindle drive from Bosch Rexroth Indramat. Belongs to the KDA Spindle Drives product family, this motor with a 2.1 A rated current sustains continuous low‑power spindle operation. An IP20 enclosure rating shields sensitive components from solid debris which preserves long‑term reliability. Weighing approximately 6 kg, this commercial drive balances heft and maneuverability to aid both installation and maintenance tasks.
Featuring a true 3‑phase design, the model delivers balanced torque output and also minimizes vibration. Internal fan for cooling removes excess heat from power electronics, thus maintains optimal operating temperatures under harsh conditions. A digital control mode enables high‑precision speed and position regulation, enhancing motion‑control accuracy. Panel mounting secures the unit within standard electrical cabinets that simplifies field installation. The availability of terminal‑connector interfaces provide robust electrical connections and prevents accidental disconnections during service. A peak current of 4.2 A accommodates transient load demands for drive stability under rapid torque changes. Assigned to a 100 V voltage class, this drive control matches medium‑voltage DC bus systems which ensures compatibility with common machine‑tool power architectures.
Physical dimensions of 390 × 105 × 265 mm (H × W × D) keep the KDA 2.1‑100‑3‑DYI‑W1 compact and it facilitates integration in space‑constrained control panels. Integrated electronic overload protection detects overcurrent events automatically, reducing damage to both drive and motor. Popular applications for this spindle drive include CNC milling spindle drive roles. This drive also excels in C‑axis contouring on turning machines which enables complex 4‑axis part geometries. High‑resolution spindle positioning supports tool‑changer indexing to accelerate production cycles. Also, a precision speed‑control range down to 0.0005 rpm enables ultra‑fine speed adjustments, improving a surface finish in micro‑machining.
Frequently Asked Questions about KDA 2.1-100-3-DYI-W1:
Q: How does the 100 V voltage class benefit the KDA 2.1‑100‑3‑DYI‑W1?
A: The 100 V voltage class matches common DC bus voltages in machine‑tool architectures. This alignment streamlines integration without additional power‑conversion hardware.
Q: How do terminal connectors improve connections?
A: Terminal connectors provide screw‑tight clamping of power and signal conductors. This firm grip prevents loosening under vibration and simplifies wiring audits.
Q: What significance does this spindle drive’s 6 kg weight hold?
A: A KDA 2.1‑100‑3‑DYI‑W1’s mass near 6 kg balances sturdiness and portability. This weight class eases manual handling while providing mechanical stability.
Q: Why does the KDA 2.1‑100‑3‑DYI‑W1 carry an IP20 rating?
A: An IP20 enclosure guards against intrusion of solid particles larger than 12 mm. This protection maintains internal cleanliness and safeguards sensitive components.
Q: How do the drive’s dimensions aid cabinet design?
A: KDA 2.1‑100‑3‑DYI‑W1’s overall dimensions of 390 × 105 × 265 mm allow the drive to fit in tight cabinet spaces. This compact footprint maximizes available panel real estate.
