Honeywell LKS-210-10 Electric Motor Buyer's Guide: 200–240V Damper Actuator Motor for Singapore Burner & HVAC Systems
Table of Contentsexpand_more
The Honeywell LKS-210-10 is a compact electric actuator motor rated 200–240V AC, 50–60Hz, producing 1.6 Nm of torque at a 70% duty cycle (ED). It is designed to position air dampers and control linkages on Honeywell burner and HVAC equipment, and it is available to Singapore buyers through 3G Electric.
What is the Honeywell LKS-210-10 electric motor?
A Honeywell LKS-210-10 electric motor is a low-torque AC actuator motor that converts 200–240V, 50–60Hz electrical input into 1.6 Nm of rotational force for damper and valve positioning. Its 70% ED rating means it is built for intermittent duty — running roughly 70% of each operating cycle — rather than continuous rotation.
Honeywell is one of the most widely specified brands in combustion and building controls, and the LKS-210-10 sits in the same ecosystem as Honeywell burner controls, recorders, and gas detection instruments. In Singapore, these motors are typically found on packaged burners, air-handling units, and industrial damper assemblies where precise air-fuel ratio control matters.
Honeywell LKS-210-10 specifications
The table below lists the published ratings for the LKS-210-10. Always cross-check against the nameplate on your existing unit before ordering a replacement.
| Parameter | Value |
|---|---|
| Model | LKS-210-10 (B1/5 S1) |
| Voltage range | 200–240 V AC |
| Frequency | 50–60 Hz |
| Torque | 1.6 Nm |
| Duty cycle | 70% ED (intermittent duty) |
| Typical function | Damper / linkage actuator motor |
| Singapore supply voltage | 230 V / 50 Hz single-phase |
How does the LKS-210-10 work?
The motor receives a 200–240V AC supply and drives a gear train that converts high-speed rotation into low-speed, high-torque output at 1.6 Nm. That output moves a damper blade or control linkage to a commanded position, regulating combustion air or process airflow.
Because the duty cycle is 70% ED, the motor is designed to run in cycles — open, hold, close — rather than spin continuously. This matches the operating profile of burner air dampers, which reposition as firing rate changes. In Singapore's 230 V / 50 Hz single-phase environment, the 200–240V rating sits comfortably within tolerance.
Where is the LKS-210-10 used in Singapore?
Singapore's industrial base — marine and offshore yards, precision manufacturing, F&B plants, and pharmaceutical facilities — relies on burner and HVAC damper control for combustion efficiency and indoor air quality. The LKS-210-10 fits these applications:
- Packaged burners on boilers and thermal oil heaters, controlling combustion air dampers.
- HVAC air-handling units where modulating dampers regulate supply and return air.
- Industrial ovens and dryers requiring repeatable airflow positioning.
- Marine and offshore ventilation and combustion systems, where corrosion resistance and IP-rated enclosures matter in humid, salt-laden air.
- F&B and pharma process heating, where stable air-fuel ratio supports consistent product quality.
How to select the right Honeywell actuator motor
- Confirm voltage and frequency. Singapore supplies 230 V / 50 Hz single-phase and 400 V three-phase. The LKS-210-10's 200–240V, 50–60Hz rating is compatible with single-phase 230 V supply.
- Match torque to load. 1.6 Nm suits light-to-medium damper loads. Heavier dampers or sticky linkages may need a higher-torque actuator.
- Check duty cycle. 70% ED is intermittent. If your application demands continuous modulation, verify the duty rating against your cycle profile.
- Verify shaft and mounting fit. Shaft diameter, keyway, and mounting flange must match the damper or linkage being driven.
- Confirm rotation direction. Clockwise or counter-clockwise output must match the damper's fail-safe position.
- Assess environment. In Singapore's humid tropical climate, specify IP-rated enclosures and corrosion-resistant housings for outdoor or marine installations.
- Check compliance. For licensed installations, confirm EMA requirements and WSH compliance for electrical work and burner commissioning.

Frequently asked questions
What is the Honeywell LKS-210-10 used for?
The LKS-210-10 is an electric actuator motor used to position air dampers and control linkages on burners, HVAC air-handling units, and industrial ovens. Its 1.6 Nm torque and 70% ED duty cycle suit intermittent damper modulation rather than continuous rotation.
Is the LKS-210-10 compatible with Singapore's 230 V / 50 Hz supply?
Yes. The motor is rated 200–240V AC, 50–60Hz, which covers Singapore's 230 V / 50 Hz single-phase supply. Confirm your circuit is single-phase and that the actuator's control signal matches your burner or HVAC controller.
How do I choose between the LKS-210-10 and a variable frequency drive?
The LKS-210-10 positions dampers at fixed torque; a VFD like the Honeywell 3G SMARTVFD 10 hp Variable Frequency Drive varies motor speed for pumps, fans, and conveyors. Choose the actuator motor for damper control and a VFD for variable-speed driven equipment.
What duty cycle does 70% ED mean?
70% ED (duty cycle) means the motor is rated to run for approximately 70% of each operating cycle, with the remainder for cooling. It is not a continuous-duty rating, so verify your application's on/off profile before specifying.
