Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
What a PCB-mount drive is
A PCB-mount servo drive is a compact servo drive module designed to be soldered or plugged into a host circuit board, rather than mounted in a cabinet. It contains the power stage and control loops for brushless, brushed or stepper-style motors, with interfaces such as CANopen, EtherCAT, SPI or analogue. Some versions are supplied with evaluation or carrier boards. Very high power density lets them fit inside robots, medical devices and instruments.
When engineers choose a PCB-mount drive
Choose a PCB-mount drive when the motor control must be embedded in the product, such as surgical robots, exoskeletons, AGVs, drones and laboratory instruments. It saves space and weight and integrates with the host board. The trade-offs are design responsibility and thermal management: the host board must provide heatsinking, connectors, EMC and protection. For machines with space for cabinets, packaged drives are simpler.
How to specify the ODrive Micro
Send these with your enquiry and an engineer can confirm the right ODrive Micro variant or an equivalent:
- Supply voltage (V DC)
- Continuous and peak current (A)
- Motor and feedback type
- Interface: CANopen, EtherCAT, SPI or analogue
- Size and mounting (mm)
- Thermal path and heatsinking
- Safety functions and approvals
Common mistakes to avoid
- Ignoring the thermal path on the host board
- Not designing EMC filtering and protection
- Assuming evaluation board performance in a sealed product
- Leaving out testing for safety and medical approvals
ODrive Micro: frequently asked questions
What is the ODrive Micro?
32 × 32 mm servo drive for small BLDC motors: 10–30 V, 3.5 A continuous and 7 A peak (100 W / 180 W), onboard magnetic encoder and daisy-chained CAN. Published series figures include voltage 32 V, power 180 W, axes 1, continuous current 3.5 A. It is made by ODrive Robotics; Specify Motion can help source it or propose an equivalent.
Who makes the ODrive Micro?
The ODrive Micro is made by ODrive Robotics and is listed here for engineers comparing options. Specify Motion is not affiliated with ODrive Robotics; brand names are used only to identify the product.
What is the voltage of the ODrive Micro?
The published series maximum voltage is 32 V. Individual models and sizes in the ODrive Micro range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Is there an alternative to the ODrive Micro?
Yes. On published figures, Novanta Everest Servo Drives (EVE-CORE, EVE-NET, EVE-XCR) - Summit Series and ADVANCED Motion Controls FlexPro Digital Servo Drives (FE, FX, FM, FD, FMP; Micro and Mini sizes) are the closest match from our supply network. An engineer confirms the fit against your application before recommending anything.
What is the benefit of a PCB-mount servo drive?
A PCB-mount drive puts motor control inside the product, saving space, weight and cabling. It integrates with the host electronics and can be very power-dense. The host board designer takes on thermal, EMC and protection design, so evaluation boards are often used first.
How is heat removed from a PCB-mount drive?
Heat is usually conducted through the drive's base or pins into the host board and a heatsink or chassis. Copper area, thermal interface materials and airflow all matter. Continuous current ratings often assume specific heatsinking, so check the conditions in the datasheet.
