Product Description:

The PMB31B-20114-00 serves as one Size 34 motor that comes equipped with a stall nominal current rating of 2.7 ARMS at 240 Volts of AC. This servo motor is one member of the PMB lineup that has been manufactured by (PS) Pacific Scientific. The PMB31B-20114-00 features a torque (stall) that remains the same at 2.11 Nm. The motor can spin at speeds of up to 4300 RPM.

The Pacific Scientific PMB Series PMB31B-20114-00 is a strong and affordable brushless servomotor that can handle a broad variety of industrial motion control needs. This servo comes with a strong Size 34 NEMA chassis. This chassis makes it function well in tough industrial conditions. For proper installation, this motor supports traditional mounting setups. With a 2.7 A winding, it may be used in situations where moderate torque and good performance are needed. This servo comes with a square key shaft structure that makes it simple to pair mechanically. It helps with sending torque reliably for an array of automation manufacturing activities. The PMB31B-20114-00 comes equipped with one digital encoder. This high-resolution feedback makes it possible to regulate the motor accurately in a closed loop, which makes the servomotor a great option for systems that need to be very precise.

Flying leads and AMP connections come with the motor, making it easy and dependable to connect it to industrial systems. The PMB31B-20114-00 is a factory-set model that always works and has good quality straight out of the box. Overall, it’s tough build, comprehensive feedback features, and simple installation make it a reliable and cost-effective choice for many industrial motion control tasks. This motor can work reliable in different manufacturing settings.
