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 DC servo drive is
A DC servo drive controls a servo motor from a low-voltage DC supply, typically between about 12 and 100 V, such as a battery or a DC power supply. It uses a PWM power stage to regulate current in brushless or brushed motors, with current, velocity and position loops closed using encoder or Hall feedback. Many are compact, some palm-sized, with CANopen, EtherCAT, Modbus or pulse inputs. Higher current is needed for the same power than with mains drives.
When engineers choose a DC servo drive
Choose a DC servo drive for mobile robots, AGVs, battery equipment, medical devices and machines designed around safety extra low voltage. It allows simple distribution and safe access to live parts. The trade-offs are current and power: high currents need heavy cables and good connections, so power is typically limited to a few kilowatts. For mains-powered machines above that, an AC servo drive is usually more economical.
How to specify the Synapticon SOMANET Integro
Send these with your enquiry and an engineer can confirm the right SOMANET Integro variant or an equivalent:
- Supply voltage range (V DC)
- Continuous and peak current (A)
- Motor type: brushless, brushed, linear
- Feedback: encoder, Hall or absolute
- Interface: CANopen, EtherCAT, Modbus, pulse
- Safety functions and STO
- Size, mounting and cooling
Common mistakes to avoid
- Ignoring battery voltage swing from full to low charge
- Undersizing cables and connectors for high current
- Forgetting regenerative energy into the battery
- Overlooking grounding and EMC on low-voltage systems
Synapticon SOMANET Integro: frequently asked questions
What is the Synapticon SOMANET Integro?
Motor-mounted all-in-one servo drive for 50–100 mm motors at 24–60 V: 20 A rms continuous (40 A peak) and up to 4.5 kW, 12–22-bit battery-free multi-turn encoder, IP67 option and STO/SBC to SIL3 / PL e. Published series figures include voltage 60 V, power 4,500 W, continuous current 20 A, peak current 40 A. It is made by Synapticon GmbH; Specify Motion can help source it or propose an equivalent.
Who makes the Synapticon SOMANET Integro?
The Synapticon SOMANET Integro is made by Synapticon (Synapticon GmbH) and is listed here for engineers comparing options. Specify Motion is not affiliated with Synapticon GmbH; brand names are used only to identify the product.
What is the voltage of the Synapticon SOMANET Integro?
The published series maximum voltage is 60 V. Individual models and sizes in the SOMANET Integro 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 Synapticon SOMANET Integro?
Yes. On published figures, Leadshine ELD2 Series Low-Voltage DC Servo Drives and Leadshine ELD3 Series Miniature DC Servo Drives are the closest match from our supply network. An engineer confirms the fit against your application before recommending anything.
Can a DC servo drive return energy to a battery?
Yes, during braking the motor regenerates energy into the DC bus, and with a battery it can be absorbed if the battery management system allows charging. Without a battery or with a full battery, voltage rises, so a braking resistor or clamp circuit may be needed. Check the drive's overvoltage threshold.
What size DC drive do I need?
Size the drive from the motor's continuous and peak current demands, the supply voltage range and the duty cycle. Allow margin above the motor's peak current and check how long the drive can deliver peak. Then confirm the interface and feedback types match the motor and controller.
