Product Description:

The SE-C4.210.030-00.101 is a permanent-magnet synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. In automated handling, packaging, and metal-cutting cells, the unit delivers controlled rotary motion to axis drives that require fast acceleration and precise velocity tracking. The motor couples directly to gearboxes or load shafts, providing closed-loop torque generation for dynamic positioning tasks in industrial automation.

At its rated operating point, the motor reaches a nominal speed of 3000 rpm. This baseline velocity reflects the synchronous relationship between the stator frequency and the four-pole rotor. During rapid transients, the drive can draw a peak current of 158 A, allowing the motor to produce up to 57.4 Nm of peak torque under a 35 / 70 °C thermal limit. The laminated rotor carries an inertia of 4.98 × 10⁻³ kg·m², balancing quick response with damping for mid-range loads. Mechanical integration is aided by a 142 mm square flange, and the A-flange seal is oil-tight during operation so lubricant from adjoining gear stages will not migrate into the winding cavity. The windings exhibit 6.2 mH of inductance and 0.51 Ω of resistance, shaping current rise and loss characteristics.

With 21 Nm of static torque available at standstill, the motor can hold payloads without movement while the drive maintains a steady current of 23 A. Each ampere contributes torque according to a constant of 0.92 Nm/A, giving predictable control loop behavior and supporting current-based tuning. The back EMF develops at 102 V/1000 rpm, a value the servo amplifier monitors during regenerative events. Overall length is 347 mm, and the hardened shaft measures Ø24 × 50 mm for keyed or clamped couplings. A total mass of 22.0 kg provides thermal inertia and helps damp vibration in high-duty cycles.
