Product Description:
Rexroth Indramat designs the MS2N10-E0BHL-BSTK0-NNNNN-NN as a 22.1-kW synchronous servo motor for precise motion and continuous duty performance. Its rated torque is specified as 137 Nm at the nominal angular speed of 1540 rounds/min and it draws 55.2 A of rated current under normal load conditions.
The MS2N10-E0BHL-BSTK0-NNNNN-NN motor generates a peak torque of 234 Nm at 20 °C and 214 Nm at 100 K. Its maximum current value is 102.50 A that enables short-term overload capacity and it offers an attainable electrical speed of up to 4000 rounds/min. The unit’s delivers a torque constant of 2.90 Nm against the utilization of every ampere of current and its back emf is specified as 176.40 V per 1000 rotations that represents the induced voltage at operating speed. Its winding resistance between phases is 0.244 Ω at 20 °C and the minimum winding inductance is measured as 0.00743 H. The MS2N10 motor has 6.20 nF of capacitance value that characterizes electrical insulation properties and it for controlled acceleration/decelerations the rotor inertia is 141 kg·cm². It uses water cooling for thermal management and its coolant inlet temperature range is 10 °C to 40 °C with a maximum temperature rise of up to 8K. The coolant path material is stainless steel for durability and its maximum inlet pressure is 6 bar, while its the coolant duct volume is 0.35 L.
The MS2N10-E0BHL-BSTK0-NNNNN-NN motor has a built-in 128 signal periods encoder system that offers singleturn absolute feedback. It ensures functional safety up to SIL 2 and PL d categories. This motor operates from a 400 VAC supply source and possess M58/M17 rotatable plugs for flexible routing. Its shaft has a keyway design with half-key balancing and includes a shaft sealing ring to achieve IP65 protective rating.
Frequently Asked Questions about MS2N10-E0BHL-BSTK0-NNNNN-NN:
Q: How does the half-key balancing on the shaft improve performance?
A: The half-key balancing reduces vibration and eccentric load on bearings at high speed. It ensures smoother rotation under dynamic load in the MS2N10.
Q: Why is water cooling preferred rather than air cooling in MS2N10-E0BHL-…?
A: The water cooling offers superior heat removal in compact design and high duty cycles. It allows sustained high torque output without thermal derating.
Q: What role does the 128 signal periods absolute encoder play?
A: The absolute feedback allows immediate position reading after power-up without homing. It enhances safety and precision control.
Q: Why is capacitance (6.2 nF) specified in the motor details?
A: The capacitance reflects internal insulation coupling and affects EMC behavior. Its designers use it to size filters or suppress interference.
Q: Why specify winding inductance (7.43 mH) in motor performance?
A: The inductance influences current rise time and electrical dynamics for limiting how fast current can change under PWM control. In MS2N10-E0BHL, 7.43 mH guides drive tuning.
