Product Description:

The TA41 V40 ER TW is a synchronous servo motor manufactured by KEB for the TA Synchronous Servo Motors series. It uses permanent-magnet technology and resolver feedback to deliver fast, repeatable rotation in packaging lines, pick-and-place modules, and other motion axes. In a closed-loop system, the motor converts electrical input into controlled shaft torque for positioning and speed regulation. This layout supports smooth response during acceleration, deceleration, and frequent direction changes.

The stator operates from 400 V three-phase power, and the drive can supply up to 19.5 A during peak demand. Winding behavior is influenced by 3.165 Ω of resistance and 10.217 mH of inductance, which helps moderate current rise and reduce ripple in the electrical system. The back-EMF factor is 95.05 mV-min, linking motor speed to generated voltage and giving the controller a predictable electrical response during dynamic operation. The six-pole rotor supports a nominal speed of 4500 rpm, providing a wide operating range for high-speed servo applications. Position feedback comes from a resolver energized at 10 kHz and 7 VAC, allowing the drive to track rotor angle continuously. The resolver signal also supports stable speed and position control when load conditions change quickly.

The motor has a mass of 7.5 kg, which helps keep moving-axis loads manageable without making the housing overly light for rigid mounting. Continuous torque is rated at 5.7 Nm, stall torque reaches 6.9 Nm, and short-term peak torque can rise to 20.7 Nm when rapid acceleration or brief overloads are required. Rotor inertia of 5.65 kg cm² gives the axis a balanced response between quick starts and stable running. Class 155 °C insulation helps the windings tolerate elevated temperature, and a PTC thermistor provides thermal monitoring before overheating can damage internal components. The motor is suitable for repeated cycling and frequent reversals in automated equipment.
