What a DC servo motor is

A DC servo motor, in current usage, is usually a low-voltage brushless permanent-magnet motor designed to run from a DC bus, typically 24 to 96 V, under closed-loop servo control. Electronically it works like an AC servo, with a three-phase stator commutated by the drive and encoder or Hall feedback on the shaft. The lower voltage means higher current for the same power, but suits battery-powered and safety-extra-low-voltage machines. Small precision brushless servomotors also fall into this group.

When engineers choose a DC servo motor

Choose a low-voltage DC servo for mobile robots, AGVs, battery equipment, medical devices and compact machines where mains voltage is impractical or unsafe. It allows simple power distribution and safe access. The trade-offs are current and power range: high current means thicker cables and higher losses, so power is typically limited to a few kilowatts. For mains-powered machines above that, an AC servo is usually simpler.

How to specify the Kinco SMH Series Low-Voltage DC Servo Motor (SMH110D)

Send these with your enquiry and an engineer can confirm the right SMH Series Low-Voltage DC Servo Motor (SMH110D) variant:

  • Bus voltage (V DC) and battery range
  • Continuous and peak torque (Nm)
  • Rated and maximum speed (rpm)
  • Continuous and peak current (A)
  • Feedback type and resolution
  • Brake, IP code and frame size (mm)
  • Drive and network interface

Common mistakes to avoid

  • Sizing at nominal battery voltage without checking the low-charge end
  • Undersizing cables for the higher current
  • Ignoring regenerative energy into a battery or supply
  • Mixing motor and drive feedback types that are not compatible

The Kinco SMH Series Low-Voltage DC Servo Motor (SMH110D) is made by Kinco (Kinco Automation) available through our supply network. Send us your requirement for pricing, lead time, datasheets and CAD.

What is the rated torque of the Kinco SMH Series Low-Voltage DC Servo Motor (SMH110D)?

The published series minimum rated torque is 4 Nm. Individual models and sizes in the SMH Series Low-Voltage DC Servo Motor (SMH110D) 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 Kinco SMH Series Low-Voltage DC Servo Motor (SMH110D)?

We can assess suitable replacement options. On published figures, Leadshine ELVM Series Low-Voltage DC Servo Motors and Leadshine ELM1 / ELM2 AC Servo Motors are options to assess from our supply network. An engineer confirms the fit against your application before recommending anything.

What is the difference between an AC servo and a DC servo motor?

Both are typically brushless permanent-magnet motors under closed-loop control. The main difference is the supply: AC servos are wound for drives fed from mains voltage, while DC servos are wound for low-voltage DC buses. DC servos suit battery and low-voltage machines; AC servos suit higher-power mains machines.

How does battery voltage affect a DC servo motor?

Motor speed is roughly proportional to available voltage, so as a battery discharges the top speed falls. Size the motor at the lowest working battery voltage. Also allow for regenerative energy during braking, which raises bus voltage and must be absorbed by the battery or a braking circuit.
