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 200–240V, 50–60Hz electric motor rated at 1.6 Nm with a 70% duty cycle, designed to position air dampers and mechanical linkages on Honeywell burner and HVAC control assemblies. In Singapore it is typically specified for 230 V / 50 Hz single-phase supply on packaged burners, air-handling units and industrial ovens.
What is the Honeywell LKS-210-10 electric motor?
A Honeywell LKS-210-10 electric motor is a low-torque, intermittent-duty actuator motor that converts 200–240 V AC, 50–60 Hz electrical input into rotary motion (1.6 Nm) to drive dampers, vanes and linkages on combustion and HVAC equipment. It is identified by the model code LKS-210-10 and the B1/5 S1 mounting designation.
Honeywell is one of the most widely specified OEM brands in combustion and building controls, and the LKS-210-10 sits in the same family as Honeywell damper actuators, burner controls and recorder accessories. Because it is a 70% ED (70% duty) device, it is intended for cycling applications — not continuous rotation — which matches the open/close behaviour of a burner air damper during pre-purge, firing and post-purge.
Honeywell LKS-210-10 specifications at a glance
The table below lists the published ratings for the LKS-210-10. All values are taken from the model designation and datasheet notes; confirm against the nameplate on your existing unit before ordering a replacement.
| Parameter | Value | Notes |
|---|---|---|
| Model | LKS-210-10 | Honeywell electric motor |
| Mounting designation | B1/5 S1 | Flange / shaft interface code |
| Supply voltage | 200–240 V AC | Matches Singapore 230 V / 50 Hz single-phase |
| Frequency | 50–60 Hz | Dual-frequency rated |
| Torque | 1.6 Nm | Rated output torque |
| Duty cycle | 70% ED | Intermittent duty — not continuous |
| Typical function | Damper / linkage actuation | Burner air control, HVAC dampers |
How does the LKS-210-10 motor work in a burner or HVAC system?
The motor receives a control signal from the burner management system or HVAC controller and rotates its output shaft to reposition an air damper or fuel/air linkage. On a packaged burner, this modulates combustion air to match firing rate; on an AHU, it drives a fresh-air or return-air damper.
Because the LKS-210-10 is rated 70% ED, it is designed to run in cycles with rest periods. Continuous-duty operation will shorten service life — if your application needs constant modulation, specify a continuous-rated actuator instead.
Where is the Honeywell LKS-210-10 used in Singapore?
Singapore's industrial base — marine and offshore yards, precision manufacturing, F&B processing and pharmaceutical plants — relies heavily on packaged burners, industrial ovens, dryers and air-handling units. The LKS-210-10 is a common replacement motor in these settings because the 200–240 V / 50–60 Hz rating matches the local 230 V / 50 Hz single-phase supply without a transformer.
- Marine & offshore: burner air dampers on auxiliary boilers and inert-gas generators.
- F&B and pharma: oven and dryer damper actuation where precise air control affects product quality.
- Precision manufacturing: process heaters and thermal oxidisers with cycling damper control.
- Commercial HVAC: AHU and duct damper positioning in humid tropical conditions — specify IP-rated enclosures where washdown or condensation is a risk.
How to select the right Honeywell motor for your application
- Confirm voltage and frequency. The LKS-210-10 accepts 200–240 V AC at 50–60 Hz, which suits Singapore's 230 V / 50 Hz single-phase supply. Three-phase plant (400 V) needs a different motor or a control transformer.
- Match torque to the load. 1.6 Nm suits light dampers and linkages. Heavier dampers, sticky linkages or high static pressure need a higher-torque actuator.
- Check the duty cycle. 70% ED is intermittent. If your process demands continuous modulation, step up to a continuous-rated unit.
- Verify the mounting interface. The B1/5 S1 designation defines flange and shaft geometry — confirm it matches your existing bracket and linkage before ordering.
- Consider the environment. Singapore's humid tropical climate accelerates corrosion. For outdoor, marine or washdown areas, confirm enclosure IP rating and consider stainless linkage hardware.
- Check compliance. Burner installations must satisfy WSH requirements and, where gas is involved, EMA-licensed gas service provider rules. Keep replacement parts traceable to the OEM.
Honeywell motor and control accessories: selection ladder
The LKS-210-10 rarely travels alone. Most Singapore buyers pair it with Honeywell controls, recorders or VFDs on the same skid. The table below compares representative Honeywell items stocked by 3G Electric, from a single replacement motor through to drive and monitoring accessories.
| Product | Function | Key spec | Typical use |
|---|---|---|---|
| Honeywell 3G SMARTVFD Variable Frequency Drive, 10 hp | Motor speed control | 10 hp, 30.8 A max output, 200–240 V AC, IP21 | Pumps, fans, conveyors — pair with damper/fan motors |
| Honeywell Circular Paper Chart, 0°C to 300°C, DR 4311 | Temperature recording | 0°C to 300°C, pack of 100 | Process temperature logging on burner/oven plant |
| Honeywell Circular Paper Chart, -85°C to 190°C, AR-100 | Temperature recording | -85°C to 190°C, pack of 100 | HVAC and refrigeration temperature logging |
| Honeywell Circular Paper Chart, 0°F to 2,000°F, AR-100 | High-temperature recording | 0°F to 2,000°F, pack of 100 | Heat-treatment and furnace documentation |
| HONEYWELL Hydrogen Fluoride Detector Tube, 0.5–20 ppm | Gas safety monitoring | 0.5–20 ppm HF, pack of 10, for LP-1200 pumps | Industrial safety checks where HF may be present |
Step up the ladder when your application moves from simple damper replacement to full loop control: add a VFD when you need variable-speed fan or pump regulation, and add chart recorders or detector tubes when compliance documentation and gas safety monitoring are required. For most Singapore burner retrofits, the LKS-210-10 plus a compatible recorder chart covers the essentials.

Frequently asked questions
What is the Honeywell LKS-210-10 used for?
The LKS-210-10 is a 200–240 V, 50–60 Hz electric motor rated 1.6 Nm at 70% ED, used to drive air dampers and linkages on burners, ovens and HVAC air-handling units. Its intermittent duty rating suits cycling open/close operation rather than continuous rotation.
Does the LKS-210-10 work on Singapore's 230 V / 50 Hz supply?
Yes. The motor is rated 200–240 V AC at 50–60 Hz, which matches Singapore's 230 V / 50 Hz single-phase supply directly. No step-down transformer is required for single-phase installations; 400 V three-phase plant needs a different motor or control transformer.
How do I know if I need the LKS-210-10 or a higher-torque motor?
Start with the damper or linkage load. If the existing motor is 1.6 Nm and the linkage moves freely, a like-for-like replacement is correct. If the damper is stiff, oversized or under high static pressure, specify a higher-torque actuator instead.
What does 70% ED mean?
70% ED (70% duty cycle) means the motor is designed to run for 70% of a defined cycle and rest for the remainder. Continuous operation beyond this rating will reduce service life — choose a continuous-duty actuator if your process never stops modulating.
Can 3G Electric deliver the LKS-210-10 quickly in Singapore?
Yes. 3G Electric holds Singapore stock and provides fast local delivery, with technical support to confirm the B1/5 S1 mounting, voltage and duty cycle match your application before dispatch. Contact us for current lead time and pricing in SGD.
What accessories should I order with the LKS-210-10?
Most burner and HVAC retrofits pair the motor with Honeywell recorder charts for temperature documentation and, where gas safety is a concern, Honeywell detector tubes. If the driven fan or pump needs speed control, add a Honeywell 3G SMARTVFD rated for the load.
