Product Specifications

Technical details and manufacturing context for Speed Controller

Definition
A speed controller is an electronic or electromechanical component within a conveyor module that precisely adjusts and maintains the rotational speed of the drive motor, thereby controlling the linear speed of the conveyor belt or chain. It ensures consistent material flow, synchronization with other processes, and allows for operational adjustments based on production requirements.
Working Principle
The controller typically receives a setpoint signal (manual input or from a PLC) and compares it to feedback from a sensor (e.g., tachometer). It then adjusts the power output to the motor (via methods like variable frequency drive, voltage regulation, or pulse-width modulation) to minimize the error between the desired and actual speed.
Common Materials
Electronic Circuit Board, Aluminum Housing, Copper Windings, Plastic Insulation
Technical Parameters
  • Output frequency range for AC motor control. (Hz) Customizable
Components / BOM
  • Power Module
    Converts incoming AC power to variable frequency/voltage AC output for the motor.
    Material: Semiconductor (IGBTs), Copper Busbars
  • Control Board
    Processes setpoint and feedback signals, executes control algorithms, and manages user interface.
    Material: FR4 PCB, Electronic Components (ICs, resistors, capacitors)
  • Heat Sink
    Dissipates heat generated by the power electronics to prevent overheating.
    Material: Aluminum Alloy
  • Operator Interface
    Provides controls (potentiometer, buttons) and display (LED, LCD) for manual speed setting and status monitoring.
    Material: Plastic, Glass
Engineering Reasoning
4-20 mA control signal input, 0-100% motor speed output, 0.5-100 Hz frequency range
Control signal deviation > ±2.5% of setpoint for >30 seconds, output frequency stability > ±0.5% of nominal
Design Rationale: Semiconductor junction thermal runaway at >150°C due to I²R losses exceeding heat dissipation capacity
Risk Mitigation (FMEA)
Trigger Voltage transient > 600V on 480V AC supply line
Mode: IGBT gate oxide breakdown causing permanent short circuit
Strategy: Metal oxide varistor with 510V clamping voltage and 40kA surge rating
Trigger Bearing lubrication failure causing motor torque increase >150% of rated
Mode: Current limiting circuit activation locking output at 0% duty cycle
Strategy: Torque monitoring relay with 120% overload trip setting and predictive maintenance schedule
