Product Description:

The 2AD134B-B35OB1-ES36-B2N1 is an induction motor, which is well suited for heavy-duty and high-capacity industrial operations. Manufactured by Bosch Rexroth Indramat, this motor has insulation class rating of F according to DIN VDE 0530 Teil 1.

This motor is integrated with a heavy-duty, electrically released holding brake that is capable of delivering a holding torque of up to 100 Nm for safe load retention during idle periods. The maximum holding braking energy capability of this motor is up to 30000 Ws, which is useful for high-inertia applications. The brake clamp delay for this motor is accurately adjusted at 70 milliseconds to ensure fast and reliable engagement during operating stops. This motor has a digital servo feedback system for precise position monitoring and ease of control system integration. The nominal torque output of this motor is rated at 76 Nm for supporting medium to heavy-duty applications to provide a stable torque output under load. This motor has the construction style of a flange and foot mounting that allows versatile alignment in different machine configurations. This motor runs effectively within an ambient temperature range between 0°C and +45°C to maintain stable performance.

The peak speed of this motor is 7500 min⁻¹ to handle dynamic applications that need rapid acceleration and deceleration. The nominal voltage of this motor is rated at 328 Veff to be compatible with power systems. This motor has a thermal time constant rated as 45 minutes to allow extended heat dissipation while reducing the risk of thermal overload during continuous use. The vibration severity level of this motor is rated as R, and the average sound pressure level of this motor at a distance of one meter is averaged at 75 dB(A) at a PWM frequency of 4 kHz to maintain acoustic performance.

Frequently Asked Questions about 2AD134B-B35OB1-ES36-B2N1:

Q: How does the digital servo feedback enhance motor performance in the 2AD134B-B35OB1-ES36-B2N1?

A: Digital servo feedback ensures real-time position accuracy, which helps reduce control lag and increases synchronization in multi-axis systems.

Q: Why is a thermal time constant of 45 minutes significant?

A: A longer thermal time constant allows the motor to sustain heavy loads over time without rapidly overheating, improving operational durability.

Q: What role does the insulation class F play in the 2AD134B-B35OB1-ES36-B2N1 motor?

A: Class F insulation permits higher allowable winding temperatures, making the motor better suited for extended duty in warm industrial settings.

Q: Why is the holding torque of 100 Nm beneficial in high-inertia systems?

A: It ensures stable load retention when the motor is idle, particularly in vertical or precision-hold applications where back-driving must be prevented.

Q: How does the flange and foot mounting design help during installation?

A: This hybrid mounting offers mechanical flexibility, enabling either base or face alignment based on space constraints and system geometry.
