Product Description:
The 8MSA3M.R0-44 Servo motor with planetary gearhead is made by B&R Automation. The servo motor is designed for motion control applications that need high torque and precise speed regulation. The motor combines a small design with mechanical capabilities often found in industrial automation applications.
The 8MSA3M.R0-44 servo motor features a flange mount with threaded holes for direct bolt attachment. The gearbox is comprised of brushed aluminum with a black anodized casing, which boosts mechanical strength. The output shaft features a shiny silver pulley with defined teeth for synchronous belt transmission. The servo motor has a rated speed of 6000 rpm and operates on 3× 230 V. The servo motor has a rated torque of 1.0 Nm and a maximum torque of 1.3 Nm. The rated current is 1.40 A, whereas the peak current is 1.70 A. The gearbox part is equipped with a visible orange rubber seal, indicating sealed bearing construction. The protection class is IP64. The insulation classification is F. The servo motor does not contain a fan. The servo motor comes with a brake to keep functionality in position-critical applications.
The 8MSA3M.R0-44 servo motor has an aluminum and steel casing, which improves structural stability. The gearbox is set to boost torque while decreasing output speed to improve motion precision. The output shaft has a pre-installed timing pulley for use in synchronous transmission setups. The insulation class F allows for higher temperature functioning. The servo motor's casing is matte black, with a silver label and color-coded connectors. The housing features two round connectors that are an orange insert for power and a green insert for feedback and control. The planetary gearhead is designed for long-duration cycles.
Frequently Asked Questions about 8MSA3M.R0-44:
Q: Does 8MSA3M.R0-44 have a brake, and what is its role?
A: Yes, the integrated brake holds the shaft position during stops or power-off. It ensures accurate positioning in motion control tasks.
Q: Why is 8MSA3M.R0-44 rated at 3× 230 V input voltage?
A: The 3×230 V input allows efficient three-phase operation. It supports consistent power delivery and reduces phase imbalance issues.
Q: How do the connectors in 8MSA3M.R0-44 assist functionality?
A: The round connectors with color-coded inserts separate power and feedback signals. They simplify installation and minimize wiring errors during setup.
Q: Why does 8MSA3M.R0-44 not include an active cooling fan?
A: The absence of a fan reduces moving parts and noise. It relies on passive cooling and insulation class F for heat management.
Q: Does 8MSA3M.R0-44 support synchronous belt systems directly?
A: Yes, the shaft includes a pre-mounted timing pulley. It enables direct integration with synchronous belts for slip-free transmission.
