Honeywell LKS-210-10 Electric Motor Buyer's Guide: 200–240V Damper & Valve Actuator Motor for Singapore
Table of Contentsexpand_more
The Honeywell LKS-210-10 is a 200–240V, 50–60Hz electric motor rated at 1.6 Nm with a 70% duty cycle (ED), designed as a replacement or OEM drive motor for Honeywell damper and valve actuator assemblies. In Singapore it is typically specified for 230 V / 50 Hz single-phase control circuits on combustion, HVAC and process equipment.
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 electrical input into 1.6 Nm of rotary output, driving dampers, butterfly valves and linkage assemblies in Honeywell control systems. Its 70% ED rating means it is engineered for cycling duty rather than continuous running.
Honeywell actuator motors of this class sit inside burner management, air-damper and modulating-valve packages. When the motor fails, the whole actuator stops modulating — so matching the original nameplate (voltage, frequency, torque, duty cycle and shaft interface) is the single most important selection step.
Honeywell LKS-210-10 specifications
The table below lists the published nameplate values for the LKS-210-10. Always cross-check against the motor you are replacing — a physically similar motor with the wrong duty cycle will overheat in service.
| Parameter | Value | Notes |
|---|---|---|
| Model | LKS-210-10 (B1/5 S1) | Honeywell actuator motor family |
| Supply voltage | 200–240 V AC | Compatible with Singapore 230 V / 50 Hz single-phase |
| Frequency | 50–60 Hz | Dual-frequency nameplate |
| Output torque | 1.6 Nm | Rated holding/driving torque |
| Duty cycle | 70% ED | Intermittent duty — not continuous rated |
| Mounting / frame | B1/5 S1 | Confirm shaft and flange fit against original |
How does a 70% ED actuator motor work?
ED (Einschaltdauer) expresses the percentage of a 10-minute cycle the motor can run before it must cool. At 70% ED, the LKS-210-10 can operate for roughly 7 minutes in every 10-minute window — enough for modulating damper and valve duty, but not for continuous rotation.
In a Honeywell burner or HVAC control loop, the motor receives a positioning signal, rotates the damper or valve to the commanded angle, then stops and holds. Because the motor is stationary most of the time, thermal build-up is low and the 70% ED rating is comfortably adequate.
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 heavily on Honeywell combustion and HVAC control packages. Typical LKS-210-10 applications include:
- Air-damper actuation on industrial burners and boilers
- Modulating control valves in process heating loops
- HVAC mixing-box and VAV damper actuators
- Retrofit and repair of Honeywell actuator assemblies in F&B and pharma cleanrooms
Because Singapore's ambient humidity is high year-round, motors installed in plant rooms, boiler houses and marine engine spaces should be inspected for corrosion on the shaft and terminal block. Where the environment is washdown or salt-laden, specify an IP-rated enclosure or remote-mount the actuator.
How to select the right Honeywell actuator motor
- Match the nameplate voltage and frequency. The LKS-210-10 accepts 200–240 V AC at 50–60 Hz, which aligns with Singapore's 230 V / 50 Hz single-phase supply. Do not substitute a 400 V three-phase motor without a control-circuit review.
- Confirm output torque. 1.6 Nm must exceed the breakaway torque of the damper or valve plus linkage losses. Undersized torque causes stalling and premature failure.
- Verify duty cycle. 70% ED suits cycling duty. If your application demands continuous modulation, step up to a continuously rated actuator.
- Check the mechanical interface. The B1/5 S1 frame designation must match the original shaft diameter, keyway and mounting flange.
- Assess the environment. For humid, washdown or outdoor Singapore installations, confirm enclosure protection and consider corrosion-resistant shaft treatment.
- Plan spares. Actuator motors are wear items — holding a spare LKS-210-10 on site avoids unplanned burner or HVAC downtime.
Honeywell control components: selection ladder

Step up the ladder when your application moves from simple on/off actuation to variable-speed control (add a Honeywell 3G SMARTVFD Variable Frequency Drive) or when you need documented process records for compliance (add the appropriate circular chart). For safety-critical environments where HF may be present, pair the actuator with Honeywell HF gas detection tubes.

Frequently asked questions
What is the Honeywell LKS-210-10 used for?
The LKS-210-10 is a 200–240 V, 50–60 Hz actuator motor rated 1.6 Nm at 70% ED. It drives dampers and control valves in Honeywell burner, boiler and HVAC assemblies, and is commonly replaced as a wear item in Singapore process and marine plants.
Is the LKS-210-10 compatible with Singapore's 230 V / 50 Hz supply?
Yes. The motor's 200–240 V, 50–60 Hz nameplate covers Singapore's standard 230 V / 50 Hz single-phase supply. Confirm the control circuit voltage and wiring before installation, and isolate power during replacement.
What does 70% ED mean?
70% ED (Einschaltdauer) means the motor can run for 70% of each duty cycle — roughly 7 minutes in every 10 — before it must cool. It is an intermittent-duty rating, not a continuous rating, and suits cycling damper and valve actuation.
How do I know if I need a higher-torque motor?
If the damper or valve stalls, hunts or fails to reach position, the 1.6 Nm rating may be insufficient once linkage losses are included. Measure breakaway torque and consult 3G Electric for a higher-torque Honeywell actuator motor.
How fast can 3G Electric deliver a Honeywell LKS-210-10 in Singapore?
Stocked items ship quickly from our Singapore warehouse, typically within 1–3 working days for standard orders. Urgent breakdown requirements can be prioritised — contact us with your model number and quantity for a confirmed lead time.
Can I use a variable frequency drive with this motor?
The LKS-210-10 is an actuator motor designed for direct control-circuit operation, not VFD speed control. For variable-speed pump, fan or conveyor applications, use a dedicated drive such as the Honeywell 3G SMARTVFD 10 hp Variable Frequency Drive.
