Single-Motor Integrated Rotary + Linear Motion Solution

Single-Motor Integrated Rotary + Linear Motion Solution

— Smaller footprint, higher precision, lower cost — redefines traditional dual-motor setups.

Industries: Precision manufacturing, medical devices, 3C electronics, automation equipment

Applications: Inspection, assembly

Key requirements: Compact design, integration, high precision, low cost

Industry pain points

Traditional dual-motor designs use separate motors for rotary and linear motion. This leads to bulky builds, double the cost, motion lag, compounded positioning errors, complex tuning, and higher failure rates — all of which limit miniaturization, integration, and high-end performance upgrades.

To tackle this common challenge, we introduce our single-motor integrated rotary + linear motion solution. Built around the PMC006 series micro integrated stepper drive controller, it combines a single motor with an inline leadscrew to deliver synchronized rotary and linear motion on one axis. The result: zero synchronization error, drastically reduced size, significantly lower cost, and stable torque output — offering a simpler, more reliable, and cost-effective motion core for high-end equipment.

Equipment overview

This solution uses a coaxial integrated transmission structure that simultaneously converts the motor’s rotary motion into screw rotation and linear travel. No second motor or complex linkages are required, eliminating synchronization issues at the mechanical root.

Key advantages

Single motor replaces two: one drive handles both motions for a minimalist structure
100% synchronization between rotation and linear movement: no timing lag, phase mismatch, or control error
Concentrated torque: all power goes into effective work — stronger thrust, smoother operation
Up to 60% smaller footprint: radial dimensions match the motor body; axial length only adds travel distance
Up to 50% cost reduction: one less motor, one less drive, one less control system, half the tuning time

Combined with the PMC006 series micro integrated drive controller, it supports open-loop/closed-loop switching, high-speed torque mode, CANopen, MODBUS RTU, offline programming, and multiple protections — delivering industrial-grade stable control in a compact package.

Solving three critical industry pain points

Space constraints: equipment keeps shrinking, but motion mechanisms can’t keep up

Traditional dual-motor setups with dual transmissions and guides take up large radial space, making it hard to fit miniaturized, portable, or embedded devices.

Our solution: coaxial integration with no radial expansion — combines rotation and linear motion to fit easily into tight spaces.
Motion lag: poor coordination between two motors limits precision

Rotary and linear motions are driven separately, forcing software delays to force synchronization. This often leads to lag, missed steps, overshoot, and jitter — compromising assembly accuracy, inspection precision, and motion consistency.

Our solution: mechanically linked design means rotation angle and linear travel are strictly proportional — step by step, with zero synchronization error.
High cost and maintenance burden

Two motors, two drives, double wiring, double tuning, double failure points — all adding up in procurement cost, development time, and maintenance expenses.

Our solution: single motor + single drive + single communication line — simpler wiring, easier logic, longer lifespan, and significantly lower overall system cost.
