Product Description:
The 2AD160C-B35OA1-BS03/S016 is a 2AD 3-phase servo motor from Rexroth Indramat that is designed with B35 construction form to support both flange and foot type mountings. Its shaft diameter is 55 mm and it uses a 16 × 10 × 80 mm key. The unit’s shaft center height is 265 mm and it provides cable entry via PG42 gland. It comes without a holding brake assembly and weighs around 240 kg.
The 2AD160C-B35OA1-BS03/S016 motor operates from a 299 V AC source and consumes a nominal power of 37000 W. It functions at a rated angular speed of 1500 RPM and provides 236.0 Nm torque and uses a normal load current of 90.0 A. The unit’s peak operating mechanical speed is specified as 6000 RPM and its rotor angular inertia is 2290 kg·cm². Its takes about 1 hour and 5 minutes of time to stabilize thermally and uses an integrated axial ventilation system that is powered from a separate source of 400/460 VAC. The ventilator provides 1120 m³/h of air flow from side B to A through the housing for efficient cooling and consumes 220 W of power at 1 PF. The 2AD160C motor requires a cable cross section 35 mm² for connection to its top mounted terminal point that opens towards A side for cable termination. Its acoustic pressure level is measured as 75 ± 3 dB(A) at one meter.
The 2AD160C-B35OA1-BS03/S016 motor’s mechanical structure is designed for continuous duty cycle and it supports operations up to 155 °C due to its class F insulation. Its feedback system relies on a resolution encoder with accuracy of ±0.02° for precise position control and to support absolute measurement with encoder monitoring. This unit comes with inbuilt thermal sensors in the winding for avoiding overheating scenarios.
Frequently Asked Questions about 2AD160C-B35OA1-BS03/S016:
Q: Why does the 2AD160C-B35OA1-BS03/S016 motor use axial ventilation instead of radial cooling?
A: The axial ventilation provides a linear airflow path through the housing for reducing hotspots along the shaft. It also ensures uniform cooling across windings, improving thermal stability.
Q: What is the advantage of a 16 × 10 × 80 mm key on the shaft?
A: This large key ensures secure power transmission with minimal slippage under heavy loads. It also helps distribute torque stress evenly across coupling.
Q: How does the built-in thermal sensor in 2AD160C-B35OA1-BS03/S016 safeguard the motor?
A: The sensor monitors winding temperature in real time and triggers protective shutdown or derating before damage. It prevents insulation breakdown and extends motor life.
Q: Why is the rotor inertia (0.229 kg·m²) specification important for motion control?
A: The inertia impacts acceleration/deceleration behavior and control loop tuning. Its known value (0.229 kg·m² here) lets servo controllers optimize the dynamic response.
Q: In what way does the PG42 cable gland benefit the cable entry system?
A: The PG42 gland provides a secure seal against dust, fluids, and contaminants. It ensures reliable insulation and strain relief for heavy power cables.
