Their MP-Series, especially MPS Servo Motors, made of stainless steel, have been created to accommodate the unique requirements for wash-down settings. By employing servo motors regardless of intense pressure, and highly caustic wash-down situations, these motors enable you to take advantage of Kinetix Integral Motion across a wider variety of applications. MPS Motor expands the extensive line of Allen-Bradley motors to unconventional applications on production equipment for food, drink, dairy, pharmaceutical brewing, and health & beauty products.

A variety of brushless servomotors are available in MPS Servo Motors, created especially to work in sanitary, including cosmetics, brewing, high-pressure cleaning, and pharmaceutical applications. For 460V and 230V specified applications, such servo motors are enclosed in stabilization, stainless steel 304-grade enclosures that come in three frame sizes (165, 130, and 100 millimeters). The motors have shafts made of 303-grade stainless steel, and each unit includes a stainless-steel shaft key from the 300-series. This key is used to secure the couplings onto the shaft. The MPS Servo Motors range in power from 1.30 to 3.50 kW and are capable of a maximum RPM rating of 3000 or 5000. The servo motors in the series provide precise position feedback using high-resolution encoders, allowing for both single and multi-turn absolute position sensing options.

MPS Servo Motors feature 24V maintaining brakes with an independent power supply, significantly more than the other MP Series. To prevent moisture and debris from getting into the bearings, every motor has two layers of protection. First, to lessen the effect of pressure fluid, there is a slinger made of plastic, and second, there is a shaft seal made of polytetrafluoroethylene. Every MPS Servo Motor is equipped with an elongated cable that includes a DIN connector made of nickel-plated zinc casting. They provide versatile cable routing options with support for numerous mounting locations to improve electromagnetic compatibility. The IP 69K, IP 67, and IP 66 rated enclosures are the environmental ratings available for the motor in this series. Various optional accessories, including positive air-pressure kits, can be obtained for MPS Servo Motors to cater to a wide range of applications.

This guide will provide valuable insights into the features, specifications, and performance characteristics of Allen-Bradley MPS Servo Motors, along with a step-by-step approach to motor selection.

Understanding Servo Motors

The servo motor serves as an autonomous electrical gadget that precisely and efficiently moves machine components. It has a BLDC motor having a sensor providing positioning feedback. Thus, it renders it precisely rotates an output shaft exactly at a certain location, angle, and speed, which is impossible with a normal motor. It is a single component of the closed-loop control of motion system. Apart from the servo motor, a complete motion system includes a control circuit, drive mechanisms, a potentiometer, an amplification unit, a shaft, and a resolver or encoder.

A servo motor is a device that uses feedback control to precisely position or move objects. Along with the motor, it consists of a sensor and a control circuit. The control circuit gets signals from the sensor and adjusts the motor's rotation to achieve the desired position. This mechanism allows for accurate and controlled movements in various applications, such as robotics and automation.

Servo motors provide several benefits over other kinds of motors, such as:

• Servo motors are the best choice for situations where precision and repeatability are crucial because they provide exact control over speed, torque, and position.
• Servo motors have been engineered to deliver strong torque across all speeds; they are ideal for operations that need to shift loads quickly and at high beginning torque.
• Servo motors are an excellent choice for usage requiring rapid acceleration due to their very quick reaction times.
• Servo motors can operate at broad speed ranges, from extremely slow to extremely fast, without compromising precision or accuracy.
