Product Description:
The 8LVA23.R0015D200-0 is a resolver compatible servo motor, built by B & R automation. It is designed for continuous duty operations to rotate at a nominal speed of 1500 RPM and produces a turning effect of 1.3 Nm. The motor has a 2.4 ms electrical constant and 0.63 h is the thermal time constant to achieve it self-cooling feature.
The 8LVA23.R0015D200-0 motor has a power rating of 209 W and comes with an analog feedback system through resolver which yields precision of around 10 arcmin. Its resolver system can bear high vibration and temperature conditions. The motor includes a built-in connector that is double angled for flexible cable orientation and it possesses a plain shaft that measure 30 mm in length with an attachable optional sealing ring. The 8LVA motor has a holding brake that operates on 24 VDC and it holds 2.2 Nm of torque while consumes 8.4 W of power along with 0.35 A of current, when in use. The motor has rotational inertia of 0.000026 kgxm^2 and produces a stall torque of rating 1.35 Nm. Its maximum torque reaches about 4 Nm upon the usage of 11.2 A RMS. The impedance of the stator is 2600 m? and stator inductance measures 0.0063 H. Its highest speed rating equals 6600 RPM and its EMF constant is 25.13 V for every 1000 RPM.
The 8LVA23.R0015D200-0 motor is IP54 protected from external intrudes and operates in the thermal range of 258.15K to 313.15K while with derating performance it can permit up to 323.15K. It can be installed at an elevate height of up to 2000 m and 90% RH. The 8LVA motor allows both vertical or horizontal mounting and it has an exterior painted with RAL 9005 matt black.
Frequently Asked Questions about 8LVA23.R0015D200-0:
Q: Why is resolver feedback used instead of an encoder in the 8LVA23.R0015D200-0 motor?
A: Resolver feedback offers better durability under high vibration and temperature, making it ideal for tough industrial settings. It ensures reliable position sensing even in harsh environments.
Q: How does the 2.4 ms electrical time constant benefit motor performance?
A: A low electrical time constant enables faster current response, improving dynamic performance and control accuracy during rapid load changes.
Q: Why does the 8LVA23.R0015D200-0 motor use a plain shaft design?
A: A plain shaft simplifies coupling with standard mechanical components. It also reduces stress points that could lead to shaft damage under high torque.
Q: How does the motor's 0.26 kgcm^2 inertia affect its performance?
A: Low rotational inertia allows quicker acceleration and deceleration, making it ideal for precise motion control applications.
Q: What advantage does the double-angled connector provide in the 8LVA23.R0015D200-0?
A: It improves cable management and allows flexible installation in tight or complex enclosures. This enhances maintenance accessibility and reduces bending stress on cables.
