Product Description:
The 2AD134D-B35OC1-AS06-A2N1 is a 3-phase induction motor produced by Bosch. It is a 2AD series AC main spindle motor with B35 mounting design to provide both flange and foot installations. This motor comes with a of plain shaft, which is fitted without a sealing ring and it offers an IP65 protection rating to avoid the entry of dust and water.
The 2AD134D-B35OC1-AS06-A2N1 induction motor has a nominal power consumption of 25.1 kW at continuous duty to deliver 160 Nm of torque. Its normal operations are rated at 1500 r/min base speed while the maximum permissible speed goes up to 7500 r/min. This motor draws a current of 68 A in normal conditions and to achieve accurate control the rotor inertia is set at 0.118 kg·m². The 2AD134D induction motor has an insulation class of F for electrical safety and to cope with high thermal value sites. It features a built-in servo feedback system to provide absolute positioning of ± 0.009° and ± 0.01´ of relative accuracy. The power terminal is located on the top surface of the motor with an oriented output direction towards side B. This 2AD134D induction motor does not offers shaft extension on side B for encoder attachment and a 10 mm² cable is required for power transmission to the terminal box.
The 2AD134D-B35OC1-AS06-A2N1 induction motor uses an axial blower for cooling that moves air between side B to side A at an average rate of 1000 m³/h by utilizing 170 VA of power. Its thermal time constant is rated at 55 minutes and produces a measured sound pressure of approx. 75 dB(A) at 1 meter distance. This 2AD134D induction motor possess grade R severity of vibrations and it is fitted with standard ball bearings.
Frequently Asked Questions about 2AD134D-B35OC1-AS06-A2N1:
Q: Why is a plain shaft without sealing ring used in the 2AD134D-B35OC1-AS06-A2N1?
A: A plain shaft without a sealing ring reduces mechanical friction and simplifies coupling in clean environments. This design is suitable for high-speed spindle operations where tight sealing is not critical.
Q: How does the axial blower improve the motor’s performance?
A: The axial blower cools the motor by moving 1000 m³/h of air from side B to side A. This prevents overheating and allows longer continuous-duty cycles without thermal derating.
Q: What is the function of the servo feedback system in 2AD134D-B35OC1-AS06-A2N1?
A: The servo feedback ensures high-precision control by providing absolute and relative positioning. This enables micro-level motion control critical for CNC and robotic applications.
Q: What does the thermal time constant of 55 minutes indicate?
A: It defines how long the motor takes to reach thermal equilibrium under load. This longer time means it can handle short-term overloads without immediate thermal risk.
Q: How does the insulation class F benefit the 2AD134D-B35OC1-AS06-A2N1 motor?
A: Class F allows the motor windings to withstand temperatures up to 155°C. This enhances electrical safety and extends motor life in high-temperature operations.
