Motor Drives & Controllers

Motor drives & controllers for small and mid-size automation: AC speed controllers (6–400 W), brushed DC motor controllers (12–72 V), brushless DC motor drivers (15–750 W), and three-phase VFDs (120–750 W). Deliver soft start/stop, precise speed regulation, quick stop/braking and protection features for conveyors, feeders, doors/gates and general machinery.

Motor Drives & Controllers for Compact Automation

Our drive portfolio covers AC, brushed DC, brushless DC and three-phase motors, providing reliable speed control, smooth starts/stops and built-in protection for continuous industrial duty. Pair each controller with the matching motor to simplify wiring and commissioning while improving uptime and process consistency.

Product Range Overview

AC Speed Controllers (6–400 W)

  • Designed for single-phase AC speed control motors in compact equipment.
  • Functions: soft start, soft stop and quick stop for smooth handling of loads.
  • Ideal for low-speed, high-torque drives when used with gearmotors.

Brushed DC Motor Controllers (12–72 V)

  • Simple PWM or voltage-based speed regulation with forward/reverse control.
  • High starting torque and responsive start/stop for indexing or duty-cycle motion.
  • Suitable for mobile, battery or small machine applications.

Brushless DC Motor Drivers (15–750 W)

  • Electronically commutated control with Hall/encoder feedback options.
  • Quiet, low-maintenance operation and linear speed/torque response.
  • Supports ramps, dynamic braking and precise closed-loop speed regulation.

Three-Phase VFDs (120–750 W)

  • For three-phase induction motors (e.g., 220/380 V) with wide speed range.
  • Features: soft start/stop, programmable acceleration/deceleration and motor protection.
  • Enhances process repeatability and energy efficiency in continuous duty.

Common Features & Benefits

  • Soft start/stop and quick stop/braking for smoother handling of loads.
  • Over-current/over-voltage/thermal protections (model-dependent).
  • Compact form factors for easy panel or machine integration.
  • Matched motor–controller combinations shorten setup and improve reliability.

Typical Applications

Conveyors and feeders, packaging and labeling modules, door/gate operators, vending and access systems, light material handling, lab/medical devices and general factory automation where precise speed regulation and dependable protection are required.
