Internal Product Review
The B-104-B-14-B3 is a Kollmorgen Goldline servo motor with a frameless resolver and standard metric mount. Rated at 1.1 kW and 7500 RPM, the motor appears especially capable in fast, controlled motion applications. A 24 VDC brake with 2.3 N-m holding torque is a strong advantage for dependable position holding.

Product Description:
The B-104-B-14-B3 is a brushless servo motor produced by Kollmorgen and delivered within the Kollmorgen Goldline B and BH Motors series. The model is intended for precision speed and torque control in automated packaging, material-handling, and general motion axes where quick acceleration, repeatable positioning, and compact mounting are required. Its compact form suits machine sections with limited space around couplings and cable exits. Power and feedback conductors exit as flying leads with a minimum length of 457 mm, which helps with routing inside tight enclosures. The housing uses a standard metric mount pattern, and the motor has no front shaft seal or rear shaft extension.
The motor runs at a rated speed of 7500 RPM, allowing high-cycle positioning while staying within the rotor's mechanical limits. It operates from 230 VAC through a compatible drive, and under continuous load it draws 4.20 A RMS to produce a continuous stall torque of 1.57 N-m. This pairing of continuous current and stall torque supports sustained load holding without overheating when the motor is matched to a compatible drive. During acceleration, the drive may deliver 12.6 A RMS so the motor can overcome inertia quickly. The holding brake is energized at 24 VDC, and the frameless resolver supplies analog sine-cosine feedback for commutation and position loops. That feedback arrangement gives the drive continuous rotor-angle information for stable commutation and controlled low-speed operation.
At standstill, the brake applies 2.3 N-m of holding torque while the coil draws only 0.93 A, helping secure vertical loads when power is removed. This brake capacity helps prevent back-driving when the axis is parked or when vertical loads must remain in place. For transient peaks, the electromagnetic stack can develop 4.45 N-m, which gives the servo system added margin against short shock loads. Rated output reaches 1.1 kW, matching medium-frame drives that support resolver feedback. The peak-torque capability supports short bursts of higher demand during indexing and rapid restart conditions.
