Product Description:

The VLM31S-BL22-02 servo motor is produced by Kollmorgen within the VLM Brushless Motors series. As a brushless permanent-magnet unit, it provides velocity and position control for pick-and-place tables, small conveyors, and other low-voltage industrial automation axes. The motor is intended for use with a compatible drive and can be integrated into machinery where a compact torque source is needed. This type of motor is commonly used where the controller must regulate both speed and shaft position within a small mechanical envelope. Its compact form makes it suitable for auxiliary axes, transfer mechanisms, and light indexing duties in automated equipment. In these roles, the motor can provide controlled acceleration and deceleration without requiring a large frame size.

An unterminated shielded cable exits the housing, allowing the connection to be matched to the application while the shield helps limit electromagnetic noise near control wiring. Because the lead is left without a factory-installed connector, the cable end can be prepared to match the selected drive or terminal arrangement. This can be useful in machines that route motor leads through tight spaces or custom harness paths. The feedback device is a 2048 PPR digital encoder, providing resolution suitable for velocity loops and standard homing functions. The encoder feedback also supports stable speed regulation during low to moderate dynamic operation. The motor uses a 1 Stack rotor core, which helps keep inertia and overall length relatively low. Its frame size is NEMA 34 or 90 mm metric, so it can fit common gearbox and adapter plate patterns used on compact motion axes.

The motor is identified as a VLM Servo Motor and uses mechanical code B. In this model, that code corresponds to a smooth shaft with a keyway, which supports positive torque transfer to pulleys or couplings. The keyed output is useful where a slip-resistant connection is preferred over a clamp-only interface. This shaft format is appropriate for timing belt pulleys, small gear inputs, and other driven elements that need consistent rotational engagement. It also keeps the mechanical interface straightforward when the motor is mounted in confined spaces.
