Allen-Bradley VPL-B0631T-CJ14AA Kinetix VPL Servo Motor
Description
063 mm frame, 480V-class VPL servo motor
The Allen-Bradley VPL-B0631T-CJ14AA is a Kinetix VPL low-inertia servo motor on a 063 mm bolt-circle frame, designed for Kinetix 5500 and 5700 drives. It has a continuous stall torque of 0.46 N-m (4.0 lb-in), a peak stall torque of 1.33 N-m (12.0 lb-in) and a rated output of 0.31 kW (0.42 Hp). 24v dc holding brake is fitted.
The Rockwell description decodes the catalog number as: (B) 480V AC class, (063) 063 mm bolt-circle frame, (1) one magnet stack, (T) winding, (C) 18-bit single-turn digital high-resolution encoder, (J) keyed shaft, (1) single SpeedTec DIN connector, (4) 24V DC holding brake and (A) standard.

Feedback, drives and installation
The 18-bit single-turn digital high-resolution encoder (feedback code C) supports tight positioning without an external feedback device. VPL motors are designed to be driven by Kinetix 5500, 5700 and related drives with 480V-class DC buses; the installation instruction VPL-IN001 covers the 063 to 165 mm frame VPL motors, with mounting, connector and brake notes.
Mount the motor to a rigid flange and keep within the datasheet’s radial and axial shaft load limits; check the motor dimensions drawing for the 063 mm frame before laying out the machine.
Performance data and the speed note
The KNX-TD001J performance table lists a rotor inertia of 0.0000094 kg-m2 (0.000083 lb-in-s2) and a motor weight of 1.04 kg (2.30 lb) for this frame and stack group. Rated speed is 6750 rpm on the Rockwell product page, 8000 rpm in the KNX-TD001J table; where two values appear, they disagree, so treat the speed as something to confirm with Rockwell before sizing against it. Torque and power figures here are the datasheet values for the 400V-class table.
Low rotor inertia keeps the motor responsive, which suits fast positioning, indexing and small-load high-acceleration axes.
Derived from the table, not quoted by Rockwell: 2.89 is the ratio of peak to continuous stall torque, and 0.44 N-m/kg is the stall torque density. These help compare VPL frames; the axis itself must be sized from the load cycle.
The 063 frame is the smallest bolt circle in the VPL range described in VPL-IN001, so it fits where space is tight, such as small indexers, labelling heads and compact pick-and-place axes. Installation guidance for all frames, including the permitted shaft loads, is in the hosted document.

About brand
Allen-Bradley is the brand of Rockwell Automation for industrial control: ControlLogix and CompactLogix controllers, I/O systems, PanelView operator terminals, PowerFlex drives, motor control and industrial network equipment. The company began in Milwaukee in 1903, when Lynde Bradley and Dr. Stanton Allen formed the Compression Rheostat Company to make the motor speed controller Bradley had invented in 1901. It took the name Allen-Bradley in 1909 and was bought by Rockwell International in 1985. Since 2001 its owner has been Rockwell Automation, which is still headquartered in Milwaukee, Wisconsin.
Allen-Bradley company profile
| Founded | 1903, Milwaukee, Wisconsin, USA, as the Compression Rheostat Company |
|---|---|
| Founders | Lynde Bradley (inventor of the compression rheostat, 1901) and Dr. Stanton Allen (investor); Harry Bradley joined in 1904 |
| Name | Allen-Bradley Company from 1909 |
| Ownership | Acquired by Rockwell International in 1985 for about USD 1.65 billion; a brand of Rockwell Automation (NYSE: ROK) since 2001 |
| Headquarters | Milwaukee, Wisconsin, USA |
| Product families | Logix programmable automation controllers (ControlLogix, CompactLogix), legacy SLC 500 and MicroLogix PLCs, Micro800 controllers, POINT, FLEX and Compact I/O, PanelView HMIs, PowerFlex AC drives, contactors, motor starters and soft starters, safety components, Stratix Ethernet switches |
Milestones
- 1901: Lynde Bradley invents the compression rheostat to control the speed of electric motors.
- 1903: The Compression Rheostat Company is formed in Milwaukee with an initial investment of USD 1,000.
- 1904: Harry Bradley joins; a crane controller is shown at the St. Louis World's Fair.

Reading Allen-Bradley catalogue numbers
The first digits of an Allen-Bradley catalogue number identify the platform, which tells you what is compatible with what. 1756 is ControlLogix (chassis-based, used for large process and plant control), 1769 is CompactLogix 5370 with Compact I/O, 5069 is CompactLogix 5380 with Compact 5000 I/O, 1734 is POINT I/O, 1794 and 5094 are FLEX and FLEX 5000 distributed I/O, 1746 and 1747 belong to the older SLC 500 family, 1766 is MicroLogix 1400 and 2080 is Micro800. For drives, 25B is PowerFlex 525 and 22B is PowerFlex 40; in a code such as 25B-D010N114, "D" means 380–480 V, "010" is the output current rating, and N114 instead of N104 means the drive has an integrated EMC filter. Many plants in the region still run SLC 500 and older MicroLogix systems, which Rockwell has discontinued, so exact spares and migration to CompactLogix are both common requests.
Where Allen-Bradley products are used
In Oman and the GCC, Allen-Bradley controllers and drives run on oil and gas facilities, water treatment and pumping stations, cement, food and beverage and packaging plants, and on machines supplied by American OEMs. ControlLogix is often the platform for plant control systems, while PowerFlex drives are used on pumps, fans and conveyors.

Ordering Allen-Bradley products: what we need
Send the full catalogue number and the series letter from the label (for example 1756-EN2T Series D), because firmware and compatibility can change between series. For drives, add the motor power, voltage and filter option. For a discontinued SLC 500 or MicroLogix part, tell us whether you need the exact spare or a migration proposal.
