Product Description:

The Bosch 2AD134B-B35RA1-ES07-H2N1 induction motor is developed for controlled motion and consistent torque delivery in industrial automation systems. It does not have a secondary shaft extension on the rear side, and its shaft is only available on one end, which simplifies installation and limits coupling options to one direction.

The 2AD134B-B35RA1-ES07-H2N1 servo motor uses insulation materials rated as Class F according to DIN VDE 0530-1 standards which indicates it can withstand a maximum temperature rise of 105°C with a total operating temperature limit of 155°C. It includes an integrated axial fan that actively blows cooling air into the motor housing which enhances heat dissipation from the stator and rotor. It is rated under S1 severity grade for vibration which indicates the rotor and bearings are balanced to handle increased vibration without performance degradation. It consumes a nominal current of 28 amperes during normal load conditions which reflects the continuous current required to achieve its rated torque and speed which ensures compatibility with standard drive electronics. It is equipped with a digital encoder that provides servo feedback and includes multiturn absolute positioning which means it can track shaft position across multiple revolutions without external reference signals. The operational noise of the motor is rated at 75 decibels measured on the A weighted scale.

The 2AD134B-B35RA1-ES07-H2N1 servo motor generates minimal vibrations and can stably rotate at high speeds. It is designed to operate continuously at 1500 rpm which is the nominal rotational speed at which the motor delivers its rated torque under standard electrical and load conditions. It has a torque rating of 76 nm which defines the mechanical power output available for driving loads and is suitable for medium to high demand motion tasks.

Frequently Asked Questions about 2AD134B-B35RA1-ES07-H2N1:

Q: How does the axial blower improve motor performance in the 2AD134B-B35RA1-ES07-H2N1?

A: The axial blower actively circulates air into the motor housing. This helps in maintaining optimal thermal conditions during continuous duty cycles.

Q: Why is a shaft sealing ring used in the 2AD134B-B35RA1-ES07-H2N1 servo motor?

A: The sealing ring prevents ingress of dust or fluids into the shaft assembly. It ensures longer bearing life and consistent shaft operation.

Q: How does multiturn absolute encoder benefit motion control applications?

A: It retains accurate position data across power cycles without homing. This enhances precision and reduces initialization time in servo-driven systems.

Q: What is the function of half key balancing in the motor shaft?

A: Balancing with a half key reduces vibration and supports smoother rotation. It also improves mechanical alignment during coupling.

Q: Why is the 2AD134B-B35RA1-ES07-H2N1 motor suitable for high-speed rotation?

A: It uses standard-grade bearings and balanced shafts. These components support stable operation at its rated speed of 1500 rpm.
