Product Description:
The 6SM 77S-3000-09-V is a synchronous servo motor manufactured by Kollmorgen within the 6SM Synchronous Servo Motors series. Designed as a compact rotary actuator for industrial automation, it converts drive current into precise shaft rotation for positioning stages, pick-and-place heads, and other closed-loop motion tasks. The motor has vertically oriented connection sockets that support direct installation on machine walls or gearboxes without intermediate brackets, while compatibility with Kollmorgen digital drives provides responsive velocity control and repeatable indexing.
Under nominal operating conditions, the motor delivers 4 kW of mechanical power at 3000 rpm. The rated current is 8 A, while the windings can accept a peak current of 40 A during acceleration or deceleration. The housing carries an IP65 protection rating, preventing dust and low-pressure water jets from reaching internal components. Continuous torque during operation is 12 Nm, while the available standstill torque is 17 Nm for holding stationary loads. A winding inductance of 8.3 mH and winding resistance of 1.1 Ω affect the electrical response used by the drive controller. An embedded thermal contact switches at 145 °C ± 5 °C to signal an overheating condition to the connected protection circuit.
Dynamic performance is influenced by a rotor inertia of 18 kg·cm², balancing responsive acceleration with stable rotation. The torque constant is 1.70 Nm/A, allowing the drive to calculate the current required for a commanded torque level. A voltage constant of 103 V/1000 rpm indicates the generated back electromotive force and supports proper DC-bus selection. Thermal response follows a 30 min time constant, and the motor has a mass of 14 kg that adds heat capacity during intermittent overloads. The stationary load can often be retained through commanded motor torque, although the suitability of this arrangement depends on the axis configuration and its safety requirements.
