Product Description:

When it comes to thermal performance and efficiency, the R43HMNA-R2-NS-NV-00 Servo motor from Pacific Scientific is the ideal choice. It is a dependable option for demanding operations due to its low thermal resistance that supports maximum power ratings.

The motor accurately regulates speed under varied loads because of its 0.61 V/rad/sec voltage constant. The R43HMNA-R2-NS-NV-00 servo motor has a steady torque output even while running continuously because of its 33 lb-in (3.7 Nm) continuous stall torque. When speed and torque dependability are crucial, a stable voltage constant paired with sustained stall torque boosts performance. The 6.9 Amps continuous current rating allows for excellent performance with minimal energy use. The winding resistance (RL) of the motor is 2.5 Ohm, which allows it to operate efficiently while also maintaining a cold temperature. The motor can operate at high speeds when required, with a no-load speed of 3000 RPM and a design voltage of 320 VDC. Its innovative design is suitable for precise motion control. This R43H motor is designed to be used in a wide variety of industrial automation tasks, and it continuously produces high-quality outcomes. A performance standard for industrial automation that guarantees both dependability and efficiency was taken into consideration during the design process of the servo motor.

The R43HMNA-R2-NS-NV-00 servo motor's precise electrical properties and low thermal resistance guarantee good operational efficiency. When it comes to applications that require reliable energy delivery without reducing performance, the 1.1 kW is the perfect choice. The no-load speed and output power ratings show that the motor can easily handle varying operational demands. The servo motor combines reliability, efficiency, and power that makes it a great part of high-tech applications.
