Product Description:
Bosch produces the 2AD132D-B35RB3-AS03-B3V1/S020 motor as a part of the 2AD series that is designed for spindle drive tasks. It achieves cooling through its provided radial blower that pushes air from B to A side through the housing with an average rate of 1000 m³ per hour. The blower requires 330 VA of power from a three phase 400 V at 50 Hz or 460 V at 60 Hz.
The 2AD132D-B35RB3-AS03-B3V1/S020 motor comes with a mechanically balanced shaft through a whole key design and it does not include a sealing ring. Its shaft supports encoder mounting on its B side as well and the shaft measures 42 mm on A side and 80 mm on B side in diameter. This unit utilizes 22-kW of power in normal load conditions, along with 54.0 A of current from a supply source of 290 V. Its angular speed has a normal rating of 1500 RPM, while it can attain up to 7500 RPM of peak speed if required. The 2AD1 motor provides 140 Nm of normal turning effect in continuous duty and its winding supports up to 428.15 K of temperature due to its class F insulation. Its heat dissipation time is measured as 3300 sec and its rotor inertia without the brake system is 1180 kgcm². This unit comes in a 132 mm frame and supports both feet/flanges mounting orientations.
The 2AD132D-B35RB3-AS03-B3V1/S020 motor’s flange dimension follows DIN 42948 standards and its shaft concentricity tolerance is defined as DIN 42955-R, with centering drill hole of DIN 332 DS M16x36. Its feedback system is composed of a high-resolution encoder for accurate positioning through its relative direct detection. The unit uses heavy duty bearings with service life of 20000 hours at rated load and they are lifetime lubricated for reduced maintenance.
Frequently Asked Questions about 2AD132D-B35RB3-AS03-B3V1/S020:
Q: How does the whole-key shaft design in the 2AD132D-B35RB3-AS03-B3V1/S020 motor help in operation?
A: The whole-key design ensures secure torque transfer and minimizes shaft slippage under high-load conditions. This increases reliability in applications requiring precise rotational accuracy.
Q: How do the lifetime-lubricated bearings improve reliability of this motor?
A: They eliminate the need for regular re-lubrication, reducing downtime and maintenance costs. The design also ensures stable performance over the 20,000-hour service life.
Q: Why is rotor inertia of 1180 kgcm² important in the 2AD132D-B35RB3-AS03-B3V1/S020?
A: The high rotor inertia supports stable spindle operation under fluctuating loads. It helps maintain speed consistency during rapid acceleration or deceleration cycles.
Q: How does the 55-minute heat dissipation time influence motor performance?
A: This indicates the motor can sustain heavy loads before heat buildup affects operation. It provides a stable thermal profile in continuous-duty environments.
Q: What is the function of DIN 42955-R concentricity tolerance in this motor’s flange design?
A: It guarantees precise shaft alignment during installation. This minimizes vibrations and ensures smoother coupling with connected mechanical systems.
