Product Description:
The 8MSA3L.R0-30 Three Phase Synchronous Motor from B & R Automation is designed for accurate, efficient motion control. With a rated power output of 0.68 kW, this motor is ideal for applications where systems need steady power delivery without wasteful energy expenditure.
The 8MSA3L.R0-30 synchronous motor has a rated speed of 3000 min⁻¹ to provide consistent operation under sustained load. This synchronous motor can handle a maximum speed of 12000 min⁻¹ to support high-speed operation integration in applications with uniform control. Under nominal load, this motor consumes a rated current of 1.62 A and can handle up to 7.7 A peak current to allow short-term overload operation without thermal instability. This synchronous motor has a stalled current of 1.8 A for stable torque at standstill, necessary to hold position during static load conditions. A 10 Nm peak torque capability enables this motor to withstand mechanical stress throughout dynamic cycles. The 1.39 Nm/A torque constant makes torque generation directly dependent on current input, thus enabling accurate torque control in real-time operations. The 84 V/1000 min⁻¹ voltage constant of this motor establishes a stable voltage output relative to speed for enhancing efficiency and responsiveness under different loads.
This motor's electrical time constant is 2.21 ms, which helps in fast adaptation to variations in control inputs, particularly within high-frequency switching conditions. The 15 Ω stator resistance of the 8MSA3L.R0-30 motor restricts heat accumulation and allows for effective power management at different speeds. This motor’s stator inductance of 33.2 mH provides for stable current regulation and electromagnetic behavior under sudden changes in operation. One of the key features of this motor is its maximum rotational acceleration of 83333 rad/s², which allows for rapid speed ramp-ups without loss of synchronization or stability.
Frequently Asked Questions about 8MSA3L.R0-30:
Q: How does the 84 V/1000 min⁻¹ voltage constant benefit the 8MSA3L.R0-30 motor?
A: It ensures proportional voltage response to speed changes, supporting accurate motor regulation. This improves control efficiency during variable-speed operations.
Q: Why is the 15 Ω stator resistance important in this motor?
A: High stator resistance minimizes current leakage and heat loss. It also helps in maintaining thermal stability during long cycles.
Q: What advantage does the 33.2 mH stator inductance provide in dynamic systems?
A: It supports smoother current transitions during load fluctuations. This helps prevent torque ripple and ensures electromagnetic consistency.
Q: How does the 2.21 ms electrical time constant affect real-time control?
A: A shorter time constant enables quicker current adaptation to input signals. It enhances performance in systems requiring high-frequency response.
Q: Why is IP 64 protection essential for the 8MSA3L.R0-30?
A: It protects the motor from dust and water spray, extending operational life. This is critical in exposed or semi-protected machine environments.
