Kollmorgen B-604-BW-91-TB
Product Introduction: The B-604-BW-91-TB is a brushless AC servo motor from Kollmorgen's B-Series with a 60 mm frame, high-speed (BW) winding, and long stack (91) for extended speed range. The "TB" shaft configuration features a threaded shaft with locking collar (clamp-style) — enabling direct mounting of pulleys, timing belts, or couplings with a clamping collar, eliminating the need for a separate key and keyway. This motor is optimized for high-speed, moderate-torque applications such as spindle drives, conveyor rollers, and high-RPM indexing.
