Custom Servo Drives

Low-voltage custom servo drive boards, micro servo amplifiers, multi-axis control PCBA, and robot-joint embedded drives for BLDC, PMSM, and frameless servo motors.

Target Buyer:For robotics teams that cannot fit an industrial cabinet drive into a battery-powered robot or compact joint module.

Custom low voltage servo drive board for robotics

Capability Highlights

Compact PCB outlines for joint housings, gripper cavities, and mobile robot modules
Support for CANopen, CAN FD, EtherCAT, UART, RS485, PWM, and project-specific firmware
Thermal, EMC, connector, encoder, braking, and production test planning

Typical Applications

Embedded robot joint drives
Micro servo drive boards for grippers
Low-voltage battery-powered robots
Medical and lab automation servo controllers
Dual-axis or multi-axis robot control boards

Engineering Focus

Bus voltage, phase current, peak current duration, switching frequency, and heat spreading
Current sensing, encoder interface, isolation, brake control, safety inputs, and firmware update path
SMT capability, AOI, ICT/FCT fixtures, conformal coating, and serial-number traceability

Key Evaluation Matrix

Metric	Typical Range	Why It Matters
Voltage and current	12-72 VDC with project-specific phase current	Power-stage sizing is the main driver of heat, cost, board size, and reliability.
Feedback interface	ABI, SPI, BiSS-C, Hall, resolver, inductive encoder	Servo performance depends on feedback latency, resolution, noise, and mechanical alignment.
Manufacturing test	AOI, ICT, FCT, burn-in, thermal sampling	Drive boards need repeatable electronics validation before they enter a robot assembly.

RFQ Checklist

Motor type, electrical parameters, encoder type, and required control loop bandwidth
Input voltage range, continuous/peak current, ambient temperature, cooling method
PCB outline, connector placement, mounting holes, and communication protocol
Firmware responsibility, bootloader, diagnostics, and production test requirements

Risk Controls

Drive board works on the bench but fails inside the joint: Test with final harness length, enclosure airflow, heat sink path, encoder cable routing, and real motion cycle.
Firmware scope is assumed but not owned: Assign responsibility for comms stack, tuning tools, bootloader, diagnostics, and customer-side commissioning.

Buyer FAQ

Can you make a servo drive board with a custom shape?

Yes. We can review irregular PCB outlines, stacked boards, board-to-board connectors, and enclosure constraints.

Can you support both prototype SMT and batch production?

Yes. We can coordinate prototype PCBA, fixture planning, controlled SMT production, and functional test records.
