Press Brake Power Source – Motor Drive for Hydraulic System

4.webp

In a hydraulic press brake system, the power source refers to the electric motor that drives the hydraulic pump, supplying energy to the entire bending operation. Though often overlooked, the performance of the motor directly affects the efficiency, precision, and energy consumption of the press brake machine.


Function of the Power Source

  • Converts electrical energy into mechanical energy to drive the hydraulic pump.

  • Enables generation of hydraulic pressure for moving the ram (slide) up and down.

  • Supports consistent and stable bending operations, even under heavy loads.


⚙️ Key Features of the Motor in Press Brakes

  • High Torque, Low Speed: For smooth and powerful pump operation.

  • Continuous Duty Rated (S1): Ensures stable performance during long production cycles.

  • Low Vibration Design: Minimizes system noise and prolongs component life.

  • Energy Efficient: IE2 / IE3 / IE4 efficiency class motors available.

  • Compact Mounting: Usually flange-mounted directly onto the hydraulic pump.


Common Configurations

  • AC Induction Motors: Most widely used in conventional press brakes.

  • Servo Motors: Found in hybrid and electric-hydraulic press brakes for precision and energy saving.

  • Power Rating: Typically 4 kW – 30 kW depending on press brake tonnage.

  • Voltage: 380V / 400V / 440V (3-phase, 50Hz or 60Hz).


Our Competitive Advantages

Our electric motors used in hydraulic press brake systems offer:

  • Stable Output with optimized start-up torque for heavy-duty applications.
