Among them, "breakaway torque" refers to the maximum instantaneous torque of the motor when overcoming stuck loads, which is suitable for occasional stuck scenarios of dampers or valves, but it is not recommended to operate under this condition for a long time. For the 4-minute timed model, prolonged stalling may cause damage to the drive shaft and should be avoided during the design phase.
2. Load capacity
The load capacity of the motor shaft end is as follows:
Single end load: 200 lb (90.8 kg)
Combination load: 300 lb (136 kg)
The maximum allowable load of the air door is divided according to the torque level:
35 lb in: Maximum air door area 7.5 ft ² (B size 1219 mm)
150 lb in: Maximum air door area of 20 ft ² (B size 2025 mm)
300 lb in: Maximum air door area of 30 ft ² (B size 2586 mm)
Environmental adaptability and installation size
1. Environmental conditions
Maximum ambient temperature: 150 ° F (66 ° C), suitable for 25% duty cycle operation
Minimum ambient temperature: -40 ° F (-40 ° C)
2. Size and Installation
The Modutrol IV series adopts a die cast aluminum shell, which is compact in structure and has good heat dissipation and protection performance. Taking M6184 as an example, the external dimensions are:
Length: 7-5/16 in (185 mm)
Width: 5-13/32 in (137 mm)
Height: 6-7/16 in (164 mm)
The installation hole design of the adapter bracket is compatible with the old M644 series, ensuring the convenience of replacement and renovation. The output shaft is a standard 3/8-inch square shaft, and the dual axis end models (M6184, M6194) support bidirectional drive, suitable for multiple sets of air door linkage or complex mechanical structures.
Certification and Standards
The Modutrol IV series motors have obtained multiple international authoritative certifications to ensure their compliance in different regions
UL certification: File No. E4436, Guide No. XAPX
CSA certification: File No. LR1620, Guide No. 400-E
These certifications cover electrical safety and performance requirements, applicable to North America and other regions that adopt UL/CSA standards.
Accessory System and Application Expansion

Typical application scenarios
The Modutrol IV series, with its flexible configuration and powerful load capacity, is widely used in the following systems:
Variable air volume system: Control the opening of the air valve in the VAV box to achieve precise temperature regulation in the area.
Fan coil unit and air handling unit: cooperate with water valve actuator to regulate the flow of cold and hot water.
Industrial ventilation system: Drive large-sized dampers in smoke exhaust or fresh air systems.
Replacement and renovation project: By adapting brackets and various linkage components, seamlessly replacing old M644 series equipment and reducing upgrade costs.
Explosion proof location: Equipped with ES650117 explosion-proof casing to meet the installation requirements of hazardous areas.
Key points for installation and debugging
In practical engineering applications, the standardization of installation and debugging directly affects the operational effectiveness of the system. The following are key precautions:
Travel setting: When adjusting the travel through the cam, it should be ensured that the midpoint of the travel remains unchanged to avoid control misalignment.
Load matching: Select the corresponding torque level based on the actual load of the damper or valve to avoid motor damage or slow control response caused by overload.
Wiring protection: If quick connect terminals are used, it is recommended to use specialized crimping tools to ensure reliable connection; If there is significant vibration in the on-site environment, a screw terminal adapter can be used to enhance connection stability.
