Honeywell LKS-210-10 Electric Motor Buyer's Guide: 200–240V Damper Actuator Motor for Singapore [2026]

The Honeywell LKS-210-10 is a 200–240V, 50–60Hz electric motor delivering 1.6 Nm of torque at a 70% duty cycle (ED), designed as a replacement drive for Honeywell damper and valve actuator assemblies in combustion and HVAC control systems. It suits Singapore's 230 V / 50 Hz single-phase supply and is typically specified for intermittent positioning duty rather than continuous running.

What is the Honeywell LKS-210-10 electric motor?

A Honeywell LKS-210-10 electric motor is a low-torque, intermittent-duty actuator motor rated 1.6 Nm at 200–240V AC, 50–60Hz, with a 70% ED rating — meaning it is designed to run for up to 70% of a defined duty cycle, not continuously. It is a component-level replacement part, not a standalone prime mover.

Honeywell builds these motors into damper actuator families used across burner management, air-handling and process control. In Singapore, they are most often encountered on combustion air dampers, flue-gas recirculation linkages and packaged HVAC units where a Honeywell actuator has failed and the motor alone needs replacing.

Honeywell LKS-210-10 specifications at a glance

The table below lists the published ratings for the LKS-210-10. Every value carries its unit; where a figure is not published, do not assume one.

How does a 70% ED motor differ from a continuous-duty motor?

ED stands for Einschaltdauer (duty cycle). A 70% ED rating means the motor is designed to operate for 70% of a defined cycle and rest for the remaining 30%. Running a 70% ED motor continuously will overheat the winding and shorten service life.

This matters in Singapore's ambient conditions. A typical plant room sits at 30–34 °C with high humidity, so thermal headroom is already reduced. If your application demands continuous modulation, specify a continuous-rated actuator instead of the LKS-210-10.

Where is the LKS-210-10 used in Singapore industry?

Singapore's buyer base for this motor is concentrated in a few sectors:

• Combustion and burner systems — driving combustion-air and flue dampers on packaged boilers and process heaters.
• F&B and pharmaceutical plants — air-handling and process damper control where Honeywell actuators are already installed.
• Marine and offshore — engine-room ventilation and damper linkages, where corrosion resistance and IP-rated enclosures matter.
• Precision manufacturing — cleanroom and process HVAC damper positioning.

Because the motor is a component inside a Honeywell actuator, most Singapore buyers are maintenance engineers replacing a failed unit rather than specifying a new system.

How to select the right replacement motor

1. Confirm the model and variant. The LKS-210-10 carries the B1/5 S1 variant code — verify this against the nameplate on the failed motor before ordering.
2. Check 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 covers the single-phase case.
3. Match torque to the linkage. 1.6 Nm suits light damper linkages. A stiff or oversized damper will stall the motor — measure the required torque or consult the actuator datasheet.
4. Respect the 70% ED duty cycle. If the damper modulates continuously, step up to a continuous-rated actuator.
5. Consider the environment. In humid or washdown areas, confirm the actuator enclosure's IP rating and consider corrosion-resistant mounting.
6. Verify compliance. For licensed installations, confirm the work falls under your EMA licence scope and that WSH risk assessments cover the electrical isolation procedure.

Related Honeywell components for combustion and process control

Most LKS-210-10 enquiries come from plants already running Honeywell instrumentation. The table below shows the Honeywell parts 3G Electric stocks alongside this motor, arranged from consumables through to drive-level controls.

Step up the ladder when your application moves from a single actuator motor to system-level control. If you are driving a pump or fan rather than a damper, the Honeywell 3G SMARTVFD 10 hp Variable Frequency Drive replaces the motor-plus-contactor arrangement entirely. If your concern is process documentation rather than actuation, the recording charts above keep your Honeywell recorders compliant.

Our specialist depth in combustion, pumps and controls means we can read a Honeywell actuator nameplate and tell you whether the LKS-210-10 is the right replacement or whether you need a different variant. We supply across 14 industrial departments, and we stock far more than is listed online. For Singapore buyers, that translates to fast local delivery from stock and technical support before and after the sale.

Frequently asked questions

What is the Honeywell LKS-210-10 used for?
The LKS-210-10 drives damper and valve linkages on Honeywell actuator assemblies, most commonly in combustion air control and HVAC systems. Its 1.6 Nm torque and 70% ED rating suit intermittent positioning duty rather than continuous modulation.

Can I use the LKS-210-10 on 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 the actuator wiring and isolation procedure against your WSH risk assessment before replacement.

What does 70% ED mean?
ED (Einschaltdauer) is the duty cycle. A 70% ED rating means the motor runs for 70% of a defined cycle and rests for 30%. Continuous operation will overheat the winding — specify a continuous-rated actuator if your damper modulates non-stop.

How do I know if the LKS-210-10 fits my actuator?
Check the variant code (B1/5 S1) and the mounting interface on your existing actuator. Torque must also match the damper load — 1.6 Nm suits light linkages. Send us the nameplate photo and we will confirm fitment.

How fast can 3G Electric deliver in Singapore?
Stocked items ship from our Singapore warehouse, typically within 1–3 working days for standard delivery. Urgent breakdowns can be expedited — contact us with your required date and we will confirm availability.

Is the LKS-210-10 a genuine Honeywell part?
3G Electric supplies genuine Honeywell industrial equipment and parts. We are a distributor and supplier, not an authorised dealer, and we verify part numbers against the Honeywell catalogue before quoting.
