Torque Control Technology

Load torque and speed fluctuation 1P Rotary Bigger Speed Fluctuation Higher Vibration

Torque Control Compression Compression – Torque  – Speed  – Current  – PWM Duty Cycle  Decompression Decompression – Torque  – Speed  – Current  – PWM Duty Cycle  Gas intake Gas discharge Operating from 15Hz to 45Hz Operating from 15Hz to 45Hz

Torque Control Normal PWM Duty Cycle Without Torque Control With Torque Control During Compression PWM Duty Cycle During Decompression
