Product Description:

The SG-B3.220.017-04.000 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. Designed for industrial automation, the unit converts drive commands into precise rotary motion. This controlled motion allows positioning tables, pick-and-place arms, and packaging stations to maintain repeatable speed and torque profiles during production cycles. The motor operates with a compatible servo drive that regulates its output according to commands from the machine control system.

The motor reaches a nominal speed of 2200 rpm, allowing moderate-to-high shaft velocities without additional gearing. At standstill, it can deliver 25 Nm while drawing a continuous current of 20.9 A; this combination represents the continuous load available while the shaft remains stationary. A torque constant of 1.26 Nm/A links controller current to mechanical torque, simplifying control calculations. The rotor inertia is 1.84 × 10⁻³ kg·m², supporting rapid acceleration and deceleration cycles. A brushless resolver sends rotor-angle feedback to the drive for closed-loop position and speed control. An integrated temperature detector monitors internal heat so the drive can reduce current when the operating temperature becomes excessive. A large integrated holding brake secures vertical or overhung loads when power is removed. The brake-equipped assembly has an overall length of 286 mm, while the version without the brake measures 271 mm. Power is carried through a 2.5 mm² lead set, which helps limit voltage drop over typical cable runs.

The enclosure carries an IP65 rating, which prevents dust ingress and protects the stator against low-pressure water jets. Mounting uses a 140 mm square flange that provides a stable interface with the machine frame. The motor transfers torque through a 24 mm diameter by 50 mm shaft stub that connects directly to keyed couplings. The bearings tolerate a maximum axial load of 200 N, so thrust forces and belt tension must remain within this limit to prevent premature wear. Resolver wires, brake conductors, and power leads exit through sealed glands, preserving enclosure protection after the motor is installed. Cable routing should avoid excessive strain at the glands so the seals and conductor terminations remain secure during machine operation.
