03Related part numbers
MPL-B430P family: keyed or keyless, with or without brake
These catalogue numbers share the 115 mm frame, magnet stack and 5,000 rpm winding of MPL-B430P-MK22AA. They differ in shaft, brake, connector or feedback. A motor with the wrong shaft or no brake will not drop into the same machine, so match every position.
| Catalogue number | Shaft | Brake | Connector | Feedback | Note |
|---|---|---|---|---|---|
| MPL-B430P-MK22AA | Keyless (smooth) shaft | No brake | Bayonet | Multi-turn absolute | This part (in stock) |
| MPL-B430P-MJ22AA | Keyed shaft | No brake | Bayonet | Multi-turn absolute | Same family |
| MPL-B430P-MJ24AA | Keyed shaft | 24 v dc holding brake | Bayonet | Multi-turn absolute | Same family |
| MPL-B430P-MK24AA | Keyless (smooth) shaft | 24 v dc holding brake | Bayonet | Multi-turn absolute | Same family |
| MPL-B430P-MK72AA | Keyless (smooth) shaft | No brake | SpeedTEC | Multi-turn absolute | SpeedTEC-connector version |
| MPL-B430P-SK22AA | Keyless (smooth) shaft | No brake | Bayonet | Single-turn absolute | Other feedback type |
| MPL-A430P-MK22AA | Keyless (smooth) shaft | No brake | Bayonet | Multi-turn absolute | 230 V version, if built in this frame |
Not every combination is built or still offered. The table shows how the catalogue number changes, not a list of parts we hold. If you need one of these variants, send the part number and we check stock and sourcing.
04Drives and cables
Drives and cables used with MPL-B430P-MK22AA
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 MPL motors on Ultra3000 drives. The drive must be configured for this exact motor catalogue number, and some newer drives need a feedback converter for Hiperface motors; check the drive manual.
This motor has the older bayonet connectors. SpeedTEC cables do not fit bayonet connectors, so keep the existing bayonet cables, or change cables if you move to a SpeedTEC-connector motor.
This motor has no brake. On a vertical axis, a motor without a brake is not a substitute for one with a brake.
- Bayonet-connector power and feedback cables (older series)
- SpeedTEC cables do not fit this motor
- Check cable condition when the motor is changed
- Feedback: multi-turn absolute encoder, read by the drive at power-up

06Before you order
Check these on your old motor's nameplate
| Check | Why it matters |
|---|---|
| Full catalogue number, including the last four characters | Shaft, connector and brake are coded at the end. Two motors that differ in those positions are not interchangeable. |
| Series letter (for example Ser. A, B) | Later series can differ in details; we confirm before you order. |
| Voltage class (A or B) | A 230 V motor on a 460 V drive, or the reverse, will not work. |
| Feedback type | The drive is set up for one feedback type. Multi-turn and single-turn are not interchangeable without changing the configuration. |
| Brake | A vertical or loaded axis needs the brake to hold position when power is off. |
