Product Description:
B&R Automation's 8MSA4S.R0-66 servo motor is an ideal choice for systems that require exact control. The speed and power output ratings are 4500 min⁻¹ and 0.90 kW, respectively. To improve operational control in a variety of applications, the motor has a holding brake with a torque of 8 Nm.
The torque constant of 0.94 Nm/A and voltage constant of 57 V/1000 min⁻¹ show efficient conversion from electrical input to mechanical output. To help in thermal load management during operation, the 8MSA4S.R0-66 servo motor has an electrical time constant of 4.51 ms and a thermal time constant of 60 minutes. In order to reduce the motor's acceleration capabilities, the moment of inertia is reduced from 1.9 kgcm2 to 0.54 kg·cm2 when the motor is braking. When there is no braking, the maximum acceleration is 54737 revolutions per second squared. It is recommended that a cable cross-section of 1.5 millimeters be utilized according to the self-cooling motor. For this reason, the performance will be at its highest. The motor's electrical specifications are influenced by its stator resistance of 4.55 Ω and inductance of 20.5 mH.
There is a 4.5 kg unbraked weight of the 8MSA4S.R0-66 servo motor and a 0.46 kg braked weight. A dependable holding force of 8 Nm is provided by the holding brake, which ensures that the motor is stopped. The rated torque is 1.9 Nm, making it ideal for accurate positioning operations. High-speed operation is possible at up to 12,000 min⁻¹. The servo motor's rated current is 2.25 A, which provides a reasonable balance of power consumption and performance, and its stall current is 2.76 A. The highly servo motor efficiently manages the motor's stall current.
