Product Description:

The PMB33F-20114-01 from Pacific Scientific is a brushless motor that is engineered to be dependable in challenging industrial settings. This servo is part of the Brushless PMB Servomotors lineup and is engineered to the NEMA standard. This signifies that it can operate smoothly with different equipment systems. The servo motor has a stall torque (constant) of 5.42 NM. The PMB33F-20114-01 weighs 6.3 kg and is built to last.

It may be mounted in a variety of ways. The PMB33F-20114-01 has a built-in digital encoder that lets users switch between modes so that feedback and control signals may be used in various ways for different applications. This versatility in feedback not only makes position and speed control more accurate, but it also makes it easy to fit into other types of motion control systems. The digital encoder makes sure that the motor works correctly and consistently, which is very important for important jobs in industries like packing, material handling, and semiconductor processing. Pacific Scientific has designed this particular PMB33F-20114-01 to function well with the PC3400 servos.

These motors are engineered to get the best of the PMB series industrial servos. The result is a drive/motor combination that works very well and is very economical. The PMB33F-20114-01 can generate useable torque ranging from 0.18 to 48.5 Nm throughout the product range. This expanded torque range means greater dynamic response, faster acceleration, and overall higher system efficiency. The motor and drive combination has several advantages. Just to mention a few of them - more freedom in how it may be used, a longer overall operating life to cut down on unwanted downtime, and better safety measures.
