Product Description:
B & R Automation develops the 8MS series motor 8MSA3S.R0-30 with a small rated torque of 0.6 Nm at 3000 r/minute rotational speed. It operates with self-cooling mechanism to maintain thermal efficiency through its slim design and flange mounting. This motor comes with a keyway arrangement of shaft and it uses size 1 connector for electrical wiring.
The 8MSA3S.R0-30 motor consumes 0.19 kW of power when operating at 3000 r/minute speed while its power utilization reaches a maximum value of 0.35 kW at 6000 r/minute speed. It pulls a peak current of 3.9 A and delivers a maximum turn effect of 2.6 Nm. This motor has a stall torque of 0.65 Nm and it draws 0.65 A as stall current. This motor has the capability of a peak speed 12000 r/minute and it gives torque constant of 0.99 Nm/A, which guarantees efficient transformation of energy. Its voltage constant is rated at 60 V per 1000 rounds and the stator resistance is 75 Ohm along with an inductance of 88 mH. The 8MSA3S.R0-30 motor possess quick response to sudden load changes through its set electrical time constant of 1.17 ms. Its thermal constant is 25 minutes to make sure that the motor can withstand heat accumulation during continuous use.
The 8MSA3S.R0-30 motor features a maximum acceleration of 66667 rad/s² without a holding brake and it is configured to operate effectively with ACOPOS servo drives. The 8MSA3S.R0-30 motor requires 400 VAC supply source and its internal structure is composed of 6 pole pairs. It is equipped with a resolver to cope with derated and resonant sites. The resolver uses a 3 x 2 x 24 AWG/19 cross sectional cable, that is oil resistant and made from PUR material.
Frequently Asked Questions about 8MSA3S.R0-30:
Q: Why is the torque constant of 0.99 Nm/A important in the 8MSA3S.R0-30 motor?
A: A high torque constant allows better torque production per ampere, enhancing the motor's energy conversion efficiency. This makes the motor ideal for precision-driven tasks.
Q: How does the resolver encoder improve performance in the 8MSA3S.R0-30 motor?
A: Resolver encoders offer durability and stable feedback in high-vibration or high-temperature conditions. This ensures accurate position sensing in derated and resonant environments.
Q: Why does the 8MSA3S.R0-30 motor use a 3 x 2 x 24 AWG/19 cable for the resolver?
A: This cable configuration supports high signal integrity and electromagnetic noise immunity. The PUR material adds resistance to oil and mechanical wear.
Q: What role does the motor's 6 pole pairs play in its operation?
A: More pole pairs allow finer control and better resolution in speed and positioning. This configuration contributes to the high-performance output at varying loads.
Q: Why is a thermal dissipation constant of 25 minutes critical for the 8MSA3S.R0-30 motor?
A: A thermal dissipation constant of 25 minutes means the 8MSA3S.R0-30 motor cools down slowly, ensuring stable temperature control. This helps prevent thermal shock and supports safe operation during intermittent or high-load cycles.
