Product Description:
The Bosch Rexroth’s induction motor 2AD160C-B05OB2-BS03/S019 is a part of the 2AD series that is designed for spindle and automation drives. Its frame size is 160 mm and it follows B05 mounting style to support flange mounting. This motor possesses a power terminal positioned above the housing, which provides cable routing towards side B.
The 2AD160C-B05OB2-BS03/S019 motor maintains cooling through an axial blower with airflow direction from A to B side. Its blower consumes around 220 VA from a 400 to 460 VAC source supply and generates an air volume of about 18.67 m³ /min. This motor operates on a nominal continuous power of 37 kW and utilizes 90 A of current from a 299 VAC supply. Its nominal torque rating is 236 Nm at rated speed 1500 revolutions/minute and its maximum speed capability is 6000 revolutions/minute. The 2AD160C motor’s moment of inertia of the rotor is specified as 0.229 kg·m² and its thermal time constant is 65 minutes that defines the thermal heating response under duty cycles. Its average sound pressure at 3.28 ft is 75 decibels and the unit carries a 240 kg of mass without brake. The motor offers electrical insulation of class F according to DIN VDE 0530 and its ambient operating range is 0 to 45 °C.
The 2AD160C-B05OB2-BS03/S019 motor uses a high-resolution encoder system for feedback that supports absolute accuracy of ±0.02 degrees and relative accuracy of ±0.01 arcminute through Its indirect position sensing technology. This motor comes with IP54 housing protection rating and its connector assemblies for power and feedback are IP65 protected. Its flange diameter is 350 mm with a 200 mm pilot fit and its bolt circle and dimensions conform to IEC standards.
Frequently Asked Questions about 2AD160C-B05OB2-BS03/S019:
Q: Why is a high-resolution encoder (±0.02° absolute) used in 2AD160C-B05OB2-BS03/S019?
A: Such precision feedback allows tight position control and smooth motion transitions in automation tasks. It supports accurate synchronization with downstream motion controllers.
Q: What advantage does B05 flange mounting bring for 2AD160C-B05OB2-BS03/S019?
A: The B05 style enables compact axial integration into machinery frames with minimal overhang. It helps maintain alignment in vertical and horizontal spindle assemblies.
Q: How does the rotor’s moment of inertia (0.229 kg·m²) affect dynamic response?
A: Its moderate inertia balances torque ripple suppression and rapid acceleration. It ensures the rotor can respond quickly to speed changes without excessive overshoot.
Q: In which scenarios is the 2AD160C-B05OB2-BS03/S019’s 6000 rpm capability exploited?
A: This high-speed ceiling is beneficial in high-speed spindles for milling or grinding. It allows wide speed range between low-speed heavy torque and high-speed finishing.
Q: Why is flange diameter and pilot fit dimension (350/200 mm) standardized?
A: The standardized flange size ensures compatibility with mounting interfaces and tooling. It simplifies integration with industry-standard spindle attachments.
