Product Description:

The 2AD134D-B35OA1-ES07-A2N1 Servo Motor that is constructed by Bosch combines top-mounted power access, moderate vibration tolerance (Grade R) and a balanced rotor inertia of 0.118 kgm². It is made to guarantee reliable, smooth operation and responsive motion control in industrial automation and control applications.

The 2AD134D-B35OA1-ES07-A2N1 servo motor cooling fan unit has a high level of environmental safeguarding. The external air temperature within which the motor can reliably function spans from the freezing point of water to a warm 40 degrees Celsius and outside this thermal range may risk malfunction or reduce service life. It is suitable for challenging environments like dusty workshops or light washdown zones as its casing is IP 65 rated to prevent dust from entering entirely. It comes with a hybrid installation method (both a base and a ringed edge) that allows for firm anchoring to a variety of mechanical platforms or housings. It has a high resolution digital sensor for position feedback system that is capable of tracking the shaft rotation with precise electric signals and its multiturn capability enables it to retain position data across multiple resolutions. It generates continuous rotational force of 175 nm which shows its ability to effectively power and maintain the motion of demanding mechanical systems over extended periods.

When operating under rated load and supplied with its nominal voltage, this 2AD134D-B35OA1-ES07-A2N1 servo motor achieves a rotational speed of 800 revolutions per minute which represents its standard operating velocity. It generally reaches its speed to 7500 rpm during short-duration operation or when the motor is running under minimal load conditions. It is equipped with widely used ball or roller bearings that are selected based on established industry norms to ensure reliable performance and mechanical longevity.

Frequently Asked Questions about 2AD134D-B35OA1-ES07-A2N1:

Q: How does the multiturn absolute encoder improve position tracking accuracy in this servo motor?

A: The multiturn encoder allows the motor to retain shaft position data even after power loss. This ensures continuous precision in positioning tasks without re-homing.

Q: Why is axial blower cooling used in the 2AD134D-B35OA1-ES07-A2N1 servo motor?

A: Axial blower cooling enhances thermal dissipation by directing airflow across heat-sensitive components. This helps maintain performance consistency during high-duty operations.

Q: What advantage does the IP65 motor protection offer in industrial applications?

A: IP65 protection prevents ingress of dust and low-pressure water jets. This makes the 2AD134D-B35OA1-ES07-A2N1 motor suitable for tough environments with minimal enclosure requirements.

Q: How does flange and foot mounting improve installation flexibility?

A: This dual mounting style allows integration in both vertical and horizontal layouts. It enhances structural stability on various mechanical assemblies.

Q: How does a plain shaft without sealing ring affect system design?

A: A plain shaft simplifies coupling with external devices. However, it requires external sealing in fluid-exposed applications.
