Product Description:

The 2AD180C-B35OB1-BS03-C2N3 is a 3-phase induction motor designed by Bosch Indramat. It features a nominal power consumption of 52 kW and delivers rated turn effect of 331 Nm. This motor comes with a top located terminal box, opening towards B side and it requires 35 mm² of cross-sectional power cable for electrical connectivity.

The 2AD180C-B35OB1-BS03-C2N3 servo motor operates at a nominal speed of 1500 rev/min, along with a maximum achievable speed of 6000 rev/min and it utilizes 110 Aeff of current from a voltage source of 351 Veff. This motor is equipped with a high-resolution motor feedback system to ensure precise control over speed and position. The encoder provides 0.02 degree of absolute accuracy and 0.01 arcminute of relative accuracy. The 2AD180C motor lacks a holding brake and it possess an angular inertia of 0.373 kg·m² for providing controlled operation at varying speeds. Its vibration severity level is rated as S1 to ensure low resonant performance. This motor has a thermal time constant of approx. 70 minutes and it is presented with an axial blower that is configured for providing an air flow of 1950 m³/h from side B to A on average. The blower operates on a separate 3 x 400 or 460 VAC source and consumes 220 VA of power.

The 2AD180C-B35OB1-BS03-C2N3 servo motor comes in a frame size of 180 mm and weighs 450 kg. It possesses a plain shaft with an imposed sealing ring to attain an overall IP65 protection rating and the shaft does not support any extension or assembly attachment on its B side. This 2AD180C servo motor uses standard ball bearings to bear high speed revolutions, with a life expectancy of 20000 hours to reduce maintenance needs up to some extent.

Frequently Asked Questions about 2AD180C-B35OB1-BS03-C2N3:

Q: Why does the 2AD180C-B35OB1-BS03-C2N3 use a plain shaft with a sealing ring?

A: The plain shaft with sealing ring ensures an IP65 rating, offering protection against dust and low-pressure water jets in industrial environments.

Q: How does the thermal time constant of 70 minutes affect motor operation?

A: It indicates slow heating, allowing for stable thermal behavior and reduced risk of overheating during prolonged operation.

Q: What is the advantage of the encoder’s 0.02° absolute accuracy in the 2AD180C-B35OB1-BS03-C2N3 motor?

A: This enables ultra-precise feedback for accurate motor positioning, crucial in high-precision automation systems.

Q: How does the 0.373 kg·m² moment of inertia affect speed transitions in the 2AD180C-B35OB1-BS03-C2N3?

A: It provides moderate resistance to sudden acceleration, enabling smoother speed changes and improved control in dynamic loads.

Q: Why does the 2AD180C servo motor use standard ball bearings instead of precision or ceramic ones?

A: Standard bearings offer a balance of cost, durability, and performance, supporting 20,000 operational hours with minimal maintenance.
