Product Description:

The 2AD164B-B05OA1-BS27-H2N1 Induction Motor comes with a flange based mounting interface for an effective installation. It is the product of Bosch Rexroth Indramat and it requires heavy duty 25 mm² cable requirements for safe power transmission. It balances performance, safety and durability to ensure reliable performance under diverse load conditions.

The 2AD164B-B05OA1-BS27-H2N1 induction motor is able to safely achieve the highest rotational velocity of 6000 revolutions in one minute. Its outer housing is sealed well enough to block dust completely and to resist water sprayed at it under pressure. It pulls 75.5 amperes of electrical current from its supply under typical operating load. During operation, it produces around 75 decibels speed and its output shaft is equipped with a key for torque transmission. At the shaft, the rotating force available continuously during normal running is 180 newton meters. It incorporates a brake, mounted to stop or hold the shaft still when the motor is not energized. Its brake is released electrically when the motor is allowed to turn and delivers 100 nm of resisting torque. The module comes with a fan mounted axially that blows air across the body to remove heat and is powered by a 400 volt supply.

The 2AD164B-B05OA1-BS27-H2N1 induction motor has a rotational inertia of 0.174 kgm². It has a built in sensing device that is capable of tracking shaft position digitally across multiple rotations. The main electrical input is located at the top of the frame. It rotates about 2000 every minute at its designed operating condition. It can provide a steady rotational force of 200 newton meters even without rotation. Its external fan housing is less tightly sealed and its stator windings can continuously handle 81.7 amperes of current.

Frequently Asked Questions about 2AD164B-B05OA1-BS27-H2N1:

Q: How does the 2AD164B-B05OA1-BS27-H2N1 motor handle continuous operation under heavy loads?

A: It provides steady torque at standstill and during normal running, making it suitable for demanding industrial cycles. Thermal management through forced cooling ensures reliability under prolonged stress.

Q: Why is flange mounting preferred for this induction motor?

A: Flange mounting allows precise shaft alignment and rigid coupling to driven equipment. This minimizes vibration and ensures stable performance in high-speed or high-torque applications.

Q: What advantage does an integrated multiturn encoder provide?

A: It records shaft position across multiple revolutions without resetting, ensuring accurate feedback even after power loss. This is critical for machine tools and automated positioning systems.

Q: How does torque derating above 1500 rpm affect applications?

A: As speed rises, available torque gradually decreases due to thermal and efficiency limits. This must be considered in systems requiring both high speed and high torque simultaneously.

Q: Why is a brake with electrical release used on this motor?

A: The brake securely holds the shaft when the motor is off, preventing unwanted movement. Electrical release ensures it disengages automatically when power is applied, simplifying control.
