  • Pick-and-place systems

Frequently Asked Questions

What is the difference between a servo motor and an AC induction motor?

Servo motors are designed for precision position and speed control, with high torque-to-inertia ratios, fast dynamic response, and encoder feedback. AC induction motors are designed for constant-speed applications and are simpler and more robust but lack the dynamic response required for motion control. Servo motors require a matched servo drive/amplifier to operate.

What does continuous vs. peak torque mean for servo motors?

Continuous torque is the sustained output the motor can produce without overheating. Peak torque is the maximum torque available for short durations (typically 1–3 seconds) for acceleration and deceleration. Motor selection requires that continuous torque exceeds your RMS load torque and peak torque exceeds your worst-case dynamic torque.
