SE-B2.030.030-14.028

Product Description:

Bosch Rexroth Indramat makes the SE-B2.030.030-14.028. With 21 Nm static torque, the Bosch Rexroth Indramat SE-B2.030.030-14.028 synchronous servo motor can withstand external loads without rotating. Torque is a key performance metric of a motor and is the result of force multiplied by the distance perpendicular to the axis of rotation. This torque in a stationary state controls the motor’s ability to hold a position against external forces. This is crucial in practice for applications that require full positional integrity under load, like automated clamping systems that hold objects without drift or robotic arms that hold heavy loads in place. This torque is defined by the interaction between the stator and rotor’s magnetic field generation and is directly influenced by changes in winding configuration or magnetic saturation.

The motor’s standard operating speed is defined by its nominal speed of 3000 rpm, which is the point where torque output and electrical input stabilize under load. The motor runs within its thermal and electromagnetic efficiency window at this speed. The torque-speed characteristic of the drive electronics, supply frequency and pole pair count are some of the variables that affect nominal speed. This speed is the reference point for the feedback loops that use encoders or resolvers to monitor rotor position and velocity in a servo environment. Precise control of the current phase and amplitude is required to maintain this speed under changing load conditions; this is usually done using vector control or field-oriented control (FOC) algorithms. These mechanisms provide dynamic torque delivery while keeping synchronization and allow for precise control of process timing in high throughput systems like CNC spindles or automated production lines where even small variations in speed can cause mechanical inefficiencies or product defects.

Electrically, the servo motor can handle a maximum current of 158 A. This is the maximum current the windings can withstand for a short period of time under temporary load conditions. The motor’s ability to handle unexpected torque demand without overloading the magnetic core or causing insulation to thermally degrade depends on its peak current ratings. When the motor is accelerated, decelerated or has torque step changes, it may need a current much higher than its continuous rating. To withstand these peaks, the design must have thermal mass, efficient heat dissipation paths and magnetic materials with high saturation flux density. The motor’s power electronics must be just as reliable with semiconductors and bus architecture that can handle these sporadic loads without tripping overcurrent protection. The motor’s mechanical time constant of 3.1 ms shows its dynamic response by measuring the time it takes for the motor to reach 63% of a step input in torque.
