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 reversible electric motor rated 200–240V, 50–60Hz, 1.6 Nm, 70% ED, built to drive burner air dampers and small actuator linkages. In Singapore it is typically specified as a form-fit replacement on Honeywell combustion and HVAC control assemblies running on 230 V / 50 Hz single-phase supply.
What is the Honeywell LKS-210-10 electric motor?
A Honeywell LKS-210-10 electric motor is a low-torque, reversible AC actuator motor rated 200–240V, 50–60Hz, delivering 1.6 Nm of output torque at a 70% duty cycle (ED). It is designed to position dampers, vanes and small linkages on Honeywell burner and HVAC control assemblies rather than to drive continuous process loads.
The model designation "(B1/5 S1)" identifies the mounting and shaft variant, so the LKS-210-10 is not a universal drop-in — it must match the host assembly's shaft, flange and rotation. Honeywell is the OEM brand behind this motor, and it is part of the same Honeywell controls ecosystem as the company's recorder charts, gas detection tubes and variable frequency drives.

How does the LKS-210-10 motor work?
The LKS-210-10 is a small AC gearmotor: mains voltage energises the winding, the gear train multiplies torque down to 1.6 Nm, and the output shaft rotates the damper or linkage to the commanded position. Because it is rated at 70% ED, it is designed for intermittent positioning duty — open, hold, close — not for continuous rotation.
In a burner application, the motor drives the air damper in step with the fuel valve so the air/fuel ratio stays within the combustion window. In an HVAC application, it positions a mixing or bypass damper on a signal from the controller. In both cases the motor is a positioning device, not a prime mover.
Where is the LKS-210-10 used in Singapore?
Singapore's industrial base concentrates this motor in a few recurring settings:
- F&B and pharmaceutical plants — burner air dampers on packaged boilers and thermal-oil heaters, where reliable positioning supports combustion efficiency and emissions compliance.
- Marine and offshore — HVAC damper actuators on vessels and yards, where the humid, salt-laden tropical climate makes IP-rated enclosures and corrosion-resistant housings important.
- Precision manufacturing — cleanroom and process HVAC dampers, plus small burner controls on heat-treatment equipment.
- Commercial buildings — AHU and duct damper actuation on 230 V / 50 Hz supplies.
Because Singapore runs 230 V / 50 Hz single-phase and 400 V three-phase, the LKS-210-10's 200–240V, 50–60Hz rating sits squarely inside the local single-phase envelope — no step-down transformer is required.
How to select the right Honeywell motor
- Match the variant code. Confirm "(B1/5 S1)" against the existing nameplate — shaft diameter, flange pattern and rotation direction must match.
- Check torque against load. 1.6 Nm suits light dampers and linkages. If the damper is stiff or oversized, step up to a higher-torque actuator.
- Confirm duty cycle. 70% ED is intermittent. Continuous positioning duty needs a motor rated for 100% ED.
- Verify supply. 200–240V, 50–60Hz covers Singapore's 230 V / 50 Hz single-phase. Do not connect to 400 V three-phase.
- Check the environment. For humid, outdoor or washdown areas, confirm the enclosure IP rating and housing material before ordering.
- Plan the control interface. Confirm how the motor is commanded (end-switch, potentiometer feedback, or controller output) so the replacement integrates cleanly.
Honeywell controls and accessories to pair with the LKS-210-10

Frequently asked questions
What is the Honeywell LKS-210-10 used for?
The LKS-210-10 drives burner air dampers and small HVAC actuator linkages. Its 1.6 Nm torque and 70% ED rating suit intermittent positioning duty, not continuous running. It is commonly found on packaged boilers, thermal-oil heaters and AHU damper assemblies.
Can I use the LKS-210-10 on Singapore's 230 V / 50 Hz supply?
Yes. The motor is rated 200–240V, 50–60Hz, which covers Singapore's 230 V / 50 Hz single-phase supply directly. Do not connect it to 400 V three-phase. Confirm the control circuit voltage before commissioning.
What does 70% ED mean on this motor?
70% ED (duty cycle) means the motor is rated for intermittent operation — roughly 70% on, 30% off within a duty period. It is not a continuous-duty motor. If your application runs the motor continuously, specify a 100% ED unit instead.
How do I confirm the LKS-210-10 (B1/5 S1) is the right variant?
Match the variant code, shaft diameter, flange pattern and rotation direction against the existing nameplate and host assembly. The "(B1/5 S1)" code defines the mounting and shaft, so a different variant will not fit. Send us a photo of the nameplate and we will confirm.
