Product Description:
The MS2N07-D0BHA-ASVG0-NNNNN-NN is a synchronous servo motor that is produced by Rexroth as a part of the MS2N family. It is equipped with a ventilation system that operates on 230 VAC and utilizes 0.18 to 0.20 A current for efficient heat dissipation. The motor delivers a rated torque of 30.1 Nm under standard conditions and 35.5 Nm at standstill.
The MS2N07-D0BHA-ASVG0-NNNNN-NN motor utilizes a rated power of 5.9 kW to provide 1870 r/min of continuous speed and its maximum electrical speed reaches a mark of 4000 r/min. It uses a low inertia rotor for high dynamic applications with a specified value of 0.0021 kg·m² and its torque constant is measured as 2.76 Nm/A at 20°C. The motor includes a basic HIPERFACE encoder with 16 signal periods and it operates as a single-turn system. The encoder does not support functional safety and produces 1 VSS of output signal with 520” of positional accuracy. The MS2N07 motor offers a back emf constant of 167.5 V/1000 rpm and its electrical configuration supports an optional 24V DC holding brake, if needed but in the pre-factory assembly it is not included. It uses a double cable connection system with M40 power connector and M17 encoder connector, both connectors are rotatable with quick-lock technology. This servo motor has a smooth shaft with a sealing ring to attain an overall IP65 protective rating.
The MS2N07-D0BHA-ASVG0-NNNNN-NN motor is presented with thermal class of 155 (F) as per EN 60034-1 and it features five magnetic pole pairs for rotor operation. Its winding supports a maximum torque of 79.7 Nm in cold condition and its peak current capacity reaches 36.4 A briefly, while its stationary current utilization is 14.1 A and its rated continuous current is 12.1 A. The motor’s body is coated with black color and it is compliant with CE, UL and EAC standards.
Frequently Asked Questions about MS2N07-D0BHA-ASVG0-NNNNN-NN:
Q: How does the ventilation system on the MS2N07-D0BHA-ASVG0-NNNNN-NN contribute to thermal performance?
A: The 230 VAC ventilation removes heat effectively to maintain optimal winding temperature. It prevents thermal buildup during continuous high-torque operation, preserving efficiency and longevity.
Q: Why is the low-inertia rotor an advantage in the MS2N07-D0BHA-ASVG0-NNNNN-NN?
A: A low-inertia rotor enables rapid acceleration and deceleration for agile motion control. This improves system responsiveness, especially in dynamic start‐stop applications.
Q: What is the benefit of having a 16-period HIPERFACE encoder in the MS2N07-D0BHA-ASVG0-NNNNN-NN?
A: The 16 signal periods give fine mechanical resolution, enhancing positional feedback. This supports smoother control loops and tighter motion precision in servo systems.
Q: How does the smooth shaft with a sealing ring improve robustness in the MS2N07-D0BHA-ASVG0-NNNNN-NN?
A: The sealing ring ensures IP65 protection, shielding internal components from dust and water ingress. This durability supports reliable performance in harsh industrial environments.
Q: How does the back EMF constant of 167.5 V/1000 rpm affect the motor’s characteristics?
A: A high back-EMF constant indicates strong voltage generation per speed, aiding regeneration and energy efficiency. It also influences driver design and braking performance.
