Product Description:
The 2AD164B-B05OB7-ES06-B2N1 is built in a size of 164 mm as a 3-phase induction motor from Bosch. It uses a flange mounting configuration and requires 25 mm² of cross-sectional cable for electrical connections to its power connector that is positioned above the housing. This motor does not include a brake system and its mass is about 240 kg with the blower.
The 2AD164B-B05OB7-ES06-B2N1 motor achieves cooling through a radial blower at the bottom and it provides an air current that moves from B to A direction. Its blower consumes 330 VA under rated conditions and operates on 3 × 400 V 50/60 Hz or 3 × 460 V 60 Hz source to delivered air volume of 0.311 m³/s. The unit’s shaft is designed with a whole key and balanced execution, it is without a sealing ring and meets DIN 6885 A standard. The shaft concentricity follows DIN 42955 R tolerance, with center drilled to DIN 332 DS M20 × 42 and its key dimensions are 16 × 10 × 80 mm. This 2AD164B motor is equipped with standard bearings that rotates the shaft at a normal speed of 1500 rev/min and its winding is designed for a specified powered consumption of 44 kW.
The 2AD164B-B05OB7-ES06-B2N1 motor is presented with a digital feedback system that requires position retention after every power off cycle and its absolute position accuracy is ±0.009°, while its relative positional accuracy is about ±0.01’ to allow precise axis positioning. Its nominal torque is 280 Nm under rated speed and it utilizes a rated current of 74 Aeff from a voltage of 453 Veff. The unit’s rotor inertia is 0.229 kg·m² and its average sound pressure level is 75 decibels.
Frequently Asked Questions about 2AD164B-B05OB7-ES06-B2N1:
Q: Why is the key dimension 16 × 10 × 80 mm specified for the shaft in 2AD164B-B05OB7-ES06-B2N1?
A: The key size ensures secure torque transmission between shaft and mounted components, preventing slippage. The length (80 mm) accommodates large couplings and helps distribute stress along the shaft.
Q: How does the digital feedback system with ±0.009° absolute accuracy benefit the 2AD164B-B05OB7-ES06-B2N1 in control applications?
A: It provides exact position knowledge after power-off, facilitating precise homing and minimal drift. This enhances performance in robotics or CNC tasks where repeatability and fine control are crucial.
Q: What role does the 25 mm² cable cross-section play in the 2AD164B-B05OB7-ES06-B2N1 power connection?
A: Its large cross section reduces electrical resistance, ensuring minimal voltage drop and heat generation under high current. It helps the motor safely handle its rated current of 74 Aeff without overheating.
Q: What is the significance of rotor inertia being 0.229 kg·m² in the 2AD164B-B05OB7-ES06-B2N1?
A: The rotor inertia determines how much torque is required to accelerate or decelerate the rotor; 0.229 kg·m² indicates moderate inertia for fast response in dynamic loads. It balances stability and agility for high-torque start-stop operations.
Q: How does the sound pressure level of 75 decibels affect the installation of 2AD164B-B05OB7-ES06-B2N1?
A: At 75 dB, the motor is audible but within acceptable limits for many industrial environments; ear protection may be needed in proximity. It influences enclosure design and distance from operators to achieve comfort standards.
