Product Description:

The KBMS-17H01-C00 is a frameless brushless torque motor built by Kollmorgen for integration into machines that need direct-drive rotary motion. It belongs to the KBM Brushless Motors series and is supplied as a kit-style rotor and stator pair for installation directly in the machine housing. This arrangement eliminates the need for a gearbox and delivers precise torque for industrial automation axes such as indexers and rotary tables.

At the electrical interface, the motor generates a back electromotive force of 21.5 Vrms/kRPM; drive selection must therefore account for this voltage coefficient to prevent overvoltage at high speed. The motor produces a continuous stall torque of 2.07 N-m with a phase current of 6.1 Arms, allowing stable holding or low-speed motion without thermal overload. When short bursts of acceleration are required, the unit can reach a peak torque of 6.35 N-m, provided that system current remains within thermal limits. The electromagnetic design converts current to torque at a rate of 0.355 N-m/Arms, simplifying current-loop tuning. With ten poles, the position feedback device must be configured for the corresponding number of electrical cycles per mechanical revolution to maintain accurate commutation.

Electrical impedance is established by a phase resistance of 1.56 ohms and an inductance of 5 mH; together, these values limit ripple current and establish the time constant that the servo drive must control. During startup or disturbance rejection, the winding can accept a peak current of 21.8 Arms, supporting maximum torque without demagnetization. Mechanical response is influenced by a rotor inertia of 0.0000512 kg-m², enabling fast acceleration while smoothing minor load fluctuations. Static friction is 0.0423 N-m, which the drive must overcome when initiating motion or maintaining precise operation near zero speed. Viscous damping is 0.00845 N-m/kRPM, and the velocity loop must compensate for this resistance as rotational speed increases.
