Product Description:
The Rexroth Indramat’s MS2N07-D0BRA-ASVH0-NNNNN-GE160N1008AN-NN synchronous servo motor is a part of the MS2N family. It operates as a three-phase permanent magnet unit from a 400 V supply source and its rated speed is specified as 3650 rev/min. This motor generates a rated torque of 18.7 Nm and its standstill torque reaches 35.5 Nm at 100K.
The MS2N07-D0BRA-ASVH0-NNNNN-GE160N1008AN-NN motor consumes a nominal power of 7.15 kW, along with a rated current of 15.4 A. Its maximum permissible current is 72.7 A and supports a peak mechanical as well as electrical rotational speed of 6000 rev/min. The motor is constructed with five pole pairs to ensure dynamic response and its torque constant is specified as 1.38 Nm/A at 20 °C. Its back EMF stands at 83.9 V/1000 rounds and its winding resistance at 20 °C is 0.327 Ω, along with an inductance of 5.06 mH minimum. The MS2N07 motor possess 3.95 nF of leakage capacitance and its winding thermal dissipation time is 45.8 seconds. It uses force ventilation through an axial blower of 230 VAC for cooling and to maintain ambient temperature. The unit possess a rotor inertia of 0.0021 kg·m² without the brake and it weighs 20 kg on its own. It uses standard bearing, with drive end size 6207 and non-drive end size 6205.
The MS2N07-D0BRA-ASVH0-NNNNN-GE160N1008AN-NN servo motor comes with a smooth shaft design, without a protective seal and it uses double cable connectivity for power/encoder through its provided M40/M17 connectors. It is equipped with a basic Hiperface encoder of single-turn revolution and it operates from a 7 to 12 V DC supply, while consumes 50 mA of current. The encoder provides 1 VSS of output signal and lacks safety protocols.
Frequently Asked Questions about MS2N07-D0BRA-ASVH0-NNNNN-GE160N1008AN-NN:
Q: What advantage does the 5 pole-pair design provide in the MS2N07-D0BRA-ASVH0-NNNNN-GE160N1008AN-NN motor?
A: It increases electrical frequency for a given rotational speed, improving torque smoothness and dynamic response. This helps the motor reach rated speed quicker and with less cogging.
Q: How does the force ventilation via the axial blower benefit motor MS2N07-D0BRA-ASVH0-NNNNN-GE160N1008AN-NN?
A: It enhances heat dissipation, keeping winding temperatures lower during high current operation. As a result, it helps protect insulation and improves continuous duty performance.
Q: Why is the leakage capacitance of 3.95 nF in MS2N07-D0BRA-ASVH0-NNNNN-GE160N1008AN-NN important?
A: This capacitance influences the motor’s response to rapid voltage changes and can affect EMI behavior. Lower leakage capacitance helps reduce potential interference with nearby electronics.
Q: What is the significance of thermal dissipation time of 45.8 seconds in this MS2N07 motor?
A: It denotes the time the motor winding temperature takes to rise to critical limits under overload before cooling down. This metric aids in designing duty cycles and protecting the motor from thermal damage.
Q: Why does MS2N07-D0BRA-ASVH0-NNNNN-GE160N1008AN-NN have a maximum permissible current of 72.7 A when rated current is only 15.4 A?
A: The motor can handle short peak loads—such as during acceleration or starting—up to 72.7 A without damage (if torque and thermal limits are managed). This provides high torque bursts while maintaining safe operating conditions.
