Some tips:
Servo Hoist vs. Induction Hoist Technical Comparison
Feature |
Servo Hoist (Absolute Servo Motor + Drive) |
Induction Hoist (Frequency Converter Drive) |
Control Method |
Closed-loop (speed, position, torque) |
Power frequency adjustment (speed only) |
Response Time |
Fast (instant torque response) 1 ms |
Slow 100 ms |
Speed Performance |
Excellent at both high and low speeds |
Difficult low-speed start, inefficient |
Accel/Decel Time |
0.2 s |
>1 s |
Position Feedback |
Built-in encoder (no zero reset needed) |
Requires external encoder |
Positioning Accuracy |
0.001 mm |
Prone to position drift over time |
Control Precision |
High displacement & positioning accuracy |
Prone to position drift over time |
Noise Level |
Low |
High |
Overload Capacity |
Excellent (3x rated load typical) |
Poor (1.5x rated load typical) |
Power Failure Behavior |
Maintains position memory |
Requires re-homing |
