Kinco SMK Series Low-Voltage DC Servo Motors replacement and alternative options

Use these supply-network options as a starting point for an engineering check. We can also help source the original Kinco part. Published series figures do not establish an exact-model or drop-in replacement: confirm ratings, fit, interfaces and approvals for your application.

Limited published data: 1 figure compared

Leadshine's AC servo motors for the EL8/EL7/EL6 drives: ELM1 is the economy line and ELM2 the general-purpose line, both with 23-bit absolute encoders, IP65/IP67 sealing and up to 3.5x overload. The catalogue extends ELM2M to 22 kW and previews a 26-bit ELM3.

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 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 SMK Series Low-Voltage DC Servo Motors

Send these with your enquiry and an engineer can confirm the right SMK Series Low-Voltage DC Servo Motors 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

Kinco SMK Series Low-Voltage DC Servo Motors: frequently asked questions

What is the Kinco SMK Series Low-Voltage DC Servo Motors?

Low-voltage brushless DC servo motors for 48 or 96 VDC systems, with a 12-slot/10-pole design, matched to the Kinco FD1X5 drive and aimed at robotics, CNC and automated lines. Published series figures include power 200 W, power 5,000 W. It is available through our supply network, and our engineers can confirm the right variant for your application.

Who makes the Kinco SMK Series Low-Voltage DC Servo Motors?

The Kinco SMK Series Low-Voltage DC Servo Motors 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 power of the Kinco SMK Series Low-Voltage DC Servo Motors?

The published series minimum power is 200 W. Individual models and sizes in the SMK Series Low-Voltage DC Servo Motors 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 SMK Series Low-Voltage DC Servo Motors?

We can assess suitable replacement options. On published figures, Leadshine ELM1 / ELM2 AC Servo Motors is 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.
