Product Overview Tojoy offers a complete high‑speed positioning centrifuge control system and motor solution, ranging from 4500‑16000 RPM. It delivers stable wide‑range output under loaded conditions with positioning accuracy within ±0.5°, and supports standard communication protocols. This solution helps centrifuge manufacturers quickly resolve technical difficulties in positioning applications.
System Composition & Module Functions 1. Communication Interface Board Data transfer unit for HMI and host computer. Supports TTL to RS232 / RS485 conversion with MODBUS protocol. Receives remote commands (start‑stop, speed, positioning) from PLC and PC, and feeds back real‑time running status and fault data. Compatible with automated production lines and laboratory workstation interconnection. 2. Control Interface Board Core logic controller of the centrifuge. Collects signals from door locks and window sensors; manages compressors, door locks, unbalance monitoring and other peripherals. Receives parameters from touchscreen and distributes motion commands to servo drives. 3. 7‑inch Capacitive Touch Display Control System HMI terminal with 1280*800 high‑definition capacitive touch, boot‑up time ≤3S. Supports full‑parameter configuration: speed, time, ramp‑up/down, pre‑cooling, ECO energy‑saving and unbalance monitoring. One‑click switch between standalone debugging and production‑line online modes. Standalone mode: 2‑48 even stations configuration, origin calibration, real‑time angle display, position locking and aging test. Customizable door‑opening logic for fast positioning commissioning. 4. Integrated Positioning Motor Centrifuge‑specific integrated servo motor with built‑in high‑precision encoder; no external origin switch required. Designed for long‑term continuous high/low‑speed operation. Provides high low‑speed torque and smooth high‑speed rotation, compatible with blood‑collection tubes, microplates and angle rotors. 5. Positioning Servo Driver Matching dedicated servo driver with embedded closed‑loop positioning algorithm; no manual loop tuning needed. Available in 600W / 700W / 1200W power ratings for low‑speed and high‑speed applications. Precisely controls acceleration, deceleration and flexible braking to achieve accurate rotor stopping.
Core Advantages ±0.5° High‑precision Positioning: Closed‑loop servo correction with high‑resolution encoder. Zero offset and no cumulative error, ideal for robotic automatic sampling and production‑line integration. Complete Turn‑key Solution: Five‑module standardized signal chain, pre‑tested at factory. No secondary development, shortens equipment commissioning and mass‑production cycle. Dual‑mode Operation: Standalone mode for R&D calibration; MODBUS bus online mode for fully‑automatic unmanned production lines. Wide Power Range for Full Scenarios: Optional 600W low‑speed, 700W high‑speed, 1200W systems for sample separation and high‑throughput centrifugation. Comprehensive Safety Protection: Door‑lock interlock, rotor unbalance detection, servo overload / overspeed / overheat protection, industrial‑grade wide‑temperature stable performance. Compact Structure, Easy Assembly: Motor‑integrated design removes extra positioning accessories, lowers assembly and maintenance costs.
