Robot Actuator Specialist

We supply the actuator.
We build what drives it.

One partner for both halves of a motion system — the hardware you buy, and the electronics and firmware that make it move.

Product Lines

Three lines we are authorized to supply.

Direct agreements with the manufacturers — which means real stock, real pricing, and engineers who actually know the parts they sell.

Core Technology

Three things have to be right
before an actuator turns.

A geared actuator is not a motor with a gearbox bolted on. Backlash, reflected inertia and shifting load all sit between the command and the movement. We handle every layer in that gap.

01

Drive Electronics

Three-phase inverter stages, gate drive, current sensing and protection. Layouts designed around thermal and noise behavior — built to survive production, not just the bench.

  • 3-PHASE INVERTER
  • GATE DRIVE
  • CURRENT SENSE
  • PROTECTION
02

Geared BLDC Control

Field-oriented control tuned for reduction drives, where backlash and load variation dominate. Velocity, position and torque loops written in-house and verified on real hardware.

  • FOC
  • SENSORLESS
  • POSITION LOOP
  • TORQUE LIMIT
03

Industrial Networking

An actuator never works alone. We design the link to the host controller — multi-axis coordination, live telemetry and diagnostics that hold up on a factory floor.

  • CAN
  • RS-485 / MODBUS
  • LoRa
  • Wi-SUN
Vision

From building other people's boards
to building what moves them.

For fifteen years MUINT designed circuits that shipped inside other companies' products. We were good at it. But no one could say what MUINT was for.

That changes now. We are becoming a robot actuator company — one that owns the full drive stack, from the power stage to the control loop to the network. Not a reseller of parts, and not a contract shop, but the engineering behind the motion itself.

Direction

Fifteen scattered years
were pointing one way.

From touch sensing, through automotive actuators, to robot drive. The path MUINT actually took.

Actuators are not new to us.

Power sliding doors. Auto tailgates. Power door locks. Motorized steps. For over a decade MUINT has been controlling motors under load, in vehicles, at production volume — with the reliability that implies.
