A-B MPL-B540K-SJ24AA AC motor with 165 mm frame length

Description.

This Rockwell Automation 165 mm MP low inertia AC motor is a 4000 RPM compact servo motor.

It has a single Turn (hyperplane protocol) encoder feedback. If braking is required, this AC synchronous servo motor is equipped with a 24 VDC brake in the motor.

In addition, this intelligent servo system is equipped with circular bayonet type cable connectors which are built into this AC servo motor and are rated at 230V AC.

Moreover, the length of this MPL series brushless motor is 4 inches.

About the MPL-B540K-SJ24AA

The MPL-B540K-SJ24AA servo motor from Allen-Bradley is an AC motor with a frame length of 165 mm.

It is rated at 4000 rpm and is part of Allen-Bradley's MPL series.

The low-inertia motors in the MPl series can support speed ratings up to 8.000 rpm and output power from 0.16 to 18.6 kW,

2.3 to 1.440 lbf continuous stall torque and 6.6 to 2.460 lbf peak stall torque.

The MPL-B540K-SJ24AA servo motor has an input rating of 400 volts AC. The approximate weight of the servo motor is 33 lbs.

The output rating is 5.4 kW. The rotor inertia is 0.014 lb-in-s2.The peak and sustained stall torque specifications for the MPL-B540K-SJ24AA servomotor are 420 lbs per inch and 172 lbs per inch, respectively.

The MPL-B540K-SJ24AA servomotor has a magnet stack length of 101.6 mm.

For feedback, the servomotor comes with a 1024 sin/cos absolute singleturn encoder. This integrated encoder supports the Hiperface protocol.

Other servomotor features include circular bayonet connectors, shaft keys, 24-volt DC brakes, and IEC metric flanges.

If a shaft seal is required, an optional seal kit is ordered from Allen-Bradley.

Advantages of installing shaft seals include protection from particles and moisture and reduced wear on the motor bearings.

The shaft seal should be lubricated with the lubricant supplied with the shaft seal kit. Since shaft seals are prone to wear, periodic inspection is recommended.

Depending on their condition, the frequency of shaft seal replacement can vary from 3 to 12 months.

Shaft seal kits manufactured by third parties should not be used with Allen-Bradley motors.
