Product Description:
Pacific Scientific develops this PMB31B-10216-03 servo motor for changing electrical energy into precise shaft rotation using encoder signals. The company creates products including this motor by using magnificent technologies to manufacture durable flexible components.
The PMB31B-10216-03 servo motor operates with a continuous stall torque of 2.11 Nm by delivering steady output during holding conditions. The unit maintains smooth start capability with static friction of 0.09 Nm for desired functioning. Its connectivity is achieved through flying leads with MS connectors. It mainly features a thermal time constant of 28 minutes which assists in allowing predictable heating and cooling characteristics during sustained load cycles. The unit works with a mass of 2.5 kg and thermal resistance of 1.08 degrees Centigrade per Watt which is efficiently balanced for continuous duty. The inclusion of a shaft seal and PTC thermistor increases operational safety and safeguards against excessive temperature rise. This series PMB servo motor is built with a NEMA frame with a Size 34 and has IP40 construction which aids in providing mechanical durability for controlled industrial automation environments. It can work effectively at installation sites reaching 1000 meters in elevation.
The PMB31B-10216-03 servo motor starts its process with 240 V AC and operates with a 320V DC bus maximum by enabling flexible supply voltage needs. The peak torque rating reaches 6.26 Nm which helps in giving short-term torque boost capacity when required. Its feedback is provided through a digital encoder with communication and is rated at 4096 pulses per revolution by ensuring precise positioning and closed-loop control. It consumes a 2.7 A current by aligning the power demands with efficient current utilization.
