Allen-Bradley MPL servo motors: catalogue numbers explained, and the parts we hold
An Allen-Bradley MPL catalogue number such as MPL-B430P-MK74AA describes the motor in full: voltage class, frame size, magnet stack, rated speed, feedback, shaft, connector and brake. This page explains each position and lists the MPL part numbers Star Automations holds in stock, all refurbished and tested in working condition. If your part number is not listed, send it and we check stock, sourcing or repair-return of your own motor.

02How to read it
How to read an MPL catalogue number
Example: MPL-B430P-MK74AA. Read each position against this table.
| Position | Example | Options |
|---|---|---|
| Series | MPL | MP-Series low-inertia servo motor |
| Voltage class | B | A = 200 V class (230 V); B = 400 V class (460 V) |
| Frame size | 4 | 15 = 63 mm, 2 = 75 mm, 3 = 100 mm, 4 = 115 mm, 45 = 130 mm, 5 = 165 mm, 6 = 215 mm, 8 = 265 mm, 9 = 300 mm |
| Magnet stack length | 30 | Length in tenths of an inch: 20 = 2.0 in, 30 = 3.0 in, 40 = 4.0 in |
| Rated speed | P | Letter code for rated speed, for example K = 4000 rpm, P = 5000 rpm, U = 7000 rpm |
| Feedback | M | V, E for 63 and 75 mm frames; M, S for 100 mm and larger; H incremental; R resolver |
| Shaft | K | J = keyed shaft; K = keyless (smooth) shaft |
| Connector | 7 | 7 = SpeedTEC DIN, right-angle, rotatable; 2 = circular bayonet (older) |
| Brake | 4 | 2 = no brake; 4 = 24 V DC holding brake |
| Factory options | AA | Standard IEC metric mounting flange |
03Speed codes
MPL rated speed letters
| Letter | Rated speed | Letter | Rated speed |
|---|---|---|---|
| A | 500 rpm | L | 4,250 rpm |
| B | 1,000 rpm | M | 4,500 rpm |
| C | 1,500 rpm | N | 4,750 rpm |
| D | 2,000 rpm | P | 5,000 rpm |
| E | 2,500 rpm | Q | 5,250 rpm |
| F | 3,000 rpm | R | 5,500 rpm |
| G | 3,250 rpm | S | 5,750 rpm |
| H | 3,500 rpm | T | 6,000 rpm |
| J | 3,750 rpm | U | 7,000 rpm |
| K | 4,000 rpm | V | 8,000 rpm |
04Feedback codes
MPL feedback codes
| Code | Feedback | Frames |
|---|---|---|
| V | multi-turn absolute, high-resolution (128 sin/cos), Hiperface | 63 mm (15) and 75 mm (2) |
| E | single-turn absolute, high-resolution (128 sin/cos), Hiperface | 63 mm (15) and 75 mm (2) |
| M | multi-turn absolute, high-resolution (1024 sin/cos), Hiperface | 100 mm (3) and larger |
| S | single-turn absolute, high-resolution (1024 sin/cos), Hiperface | 100 mm (3) and larger |
| H | 2000-line incremental encoder | Older variants |
| R | resolver | Older variants |
Multi-turn and single-turn versions are not interchangeable without changing the drive configuration. Absolute-encoder motors also need the encoder aligned to the rotor after any encoder or rotor work.
05Shaft, connector, brake
The last four characters decide whether a motor fits
Two MPL motors with the same frame and winding can still be different parts. The end of the catalogue number decides whether the motor fits the coupling, the cables and the axis.
Keyed or keyless shaft
J is a keyed shaft for a keyed coupling or pulley. K is a smooth shaft for a clamping coupling. They are not interchangeable without changing the coupling.
SpeedTEC or bayonet connector
Connector code 7 is SpeedTEC; code 2 is the older bayonet type. The cables are different, so moving from one to the other means changing cables too.
Brake or no brake
Code 4 is a 24 V DC holding brake, used on vertical or loaded axes. Code 2 has no brake. Never replace a brake motor with a non-brake motor on a vertical axis.
Voltage class
A is 230 V class and B is 460 V class. The drive must match.
06Drives and cables
Drives and cables used with MPL motors
Rockwell's compatibility tables list MPL motors with Kinetix 300, 350, 2000, 5100, 5300, 5500, 5700, 6000, 6200 and 6500 drives. Older machines often run them on Ultra3000 drives. Kinetix VPL motors are based on MPL technology but use single-cable digital feedback, so they need a different cable and drive setup.
- SpeedTEC power cables: 2090-CPBM7DF and 2090-CPWM7DF series
- SpeedTEC feedback cables: 2090-CFBM7DF and 2090-CFBM7DD series
- Bayonet-connector motors use the older bayonet cable series
- Continuous-flex versions for cable chains

How do I read an Allen-Bradley MPL catalogue number?
Left to right: MPL series, voltage letter (A 230 V, B 460 V), frame size, magnet stack length, rated speed letter, feedback letter, shaft letter (J keyed, K keyless), connector digit (7 SpeedTEC, 2 bayonet), brake digit (2 none, 4 24 V DC brake) and factory options (AA).
What is the difference between MPL-B430P-MK74AA and MPL-B430P-MK72AA?
The brake. The 4 in MK74AA is a 24 V DC holding brake; the 2 in MK72AA means no brake.
What is the difference between MK and MJ in an MPL part number?
M is the feedback (multi-turn absolute). The next letter is the shaft: J is a keyed shaft and K is a keyless shaft.
Can a SpeedTEC MPL motor replace a bayonet-connector MPL motor?
Mechanically and electrically it can be equivalent, but the cables are different. SpeedTEC cables do not fit bayonet connectors, so the cables must be changed with the motor.
Is the Allen-Bradley MPL motor discontinued?
Rockwell still lists the MPL family, but some older variants, such as bayonet-connector and incremental-feedback versions, have been discontinued and replaced. Check the exact catalogue number.
Do you repair MPL servo motors?
Yes. Bearings, brakes, encoders and connectors, with encoder alignment and a load test. Warranty terms are stated on each quotation.
