Product Description:
The 6SM 77S-3000-G-09 is a synchronous servo motor manufactured by Kollmorgen and supplied through the 6SM Synchronous Servo Motors series. It is intended for closed-loop positioning and velocity tasks in automated machinery, where the motor’s electromagnetic field follows drive commands for accurate shaft control. When connected to a suitable servo amplifier, the unit converts electrical energy into controlled mechanical torque and speed, providing a compact actuator for packaging lines, pick-and-place axes, and other precision motion stages.
The stator windings are designed for a supply connection of 400/460 V, and the motor draws a rated current of 8 A during continuous operation. Under these conditions, it delivers 4 kW of mechanical power while maintaining a synchronous speed of 3000 rpm. Rated torque reaches 12 Nm, supported by a torque constant of 1.70 Nm/A and a coil resistance of 1.1 Ω, so the drive can predict load response accurately. The motor has a 24 VDC fail-safe brake that clamps the shaft when power is removed, allowing vertical axes to hold their position. A voltage constant of 103 V per 1000 rpm indicates the back electromotive force sensed by the amplifier during dynamic control. The total inductance is 8.3 mH, which helps control current ripple at pulse-width modulation frequencies.
For short-term demands, the winding can accept a peak current of 40 A, producing high acceleration without saturation. Dynamic moves are also influenced by a rotor inertia of 18 kgcm², which balances responsiveness against load matching. Thermal behavior is characterized by a 30-minute time constant, and an internal thermostat opens at 145 °C to protect the insulation before critical temperatures are reached. Standstill operation permits 10 A of current and provides 17 Nm of holding torque, giving stable static force while the servo loops remain active. The fail-safe brake provides separate mechanical holding when electrical power is unavailable, while active holding torque remains available during powered operation.
