How the PGM-38P-12-51-392-CBB Powers Reliable Linear Actuation for Personal Aircraft Landing Gear
The Challenge: Engineering Critical Motion Control for Personal Aircraft
Designing components for personal aircraft demands an uncompromising blend of precision, reliability, and compact integration. Engineers in the aerospace sector frequently encounter the complex challenge of developing linear actuators that can perform critical functions, such as deploying and retracting landing gear, within extremely confined spaces. These actuators must deliver precise, controlled motion, handle significant and varying loads, and ensure unwavering reliability under intermittent, yet high-stress, operational cycles.
Consider a scenario where an aerospace manufacturer was developing a new personal aircraft, requiring a highly efficient and robust linear actuator system for its landing gear. The primary hurdle was the severe spatial limitation within the aircraft’s wing or fuselage, which dictated an exceptionally compact motor solution. Beyond size, the motor needed to provide substantial starting torque to initiate movement, manage the dynamic loads encountered during takeoff and landing, and ensure smooth, precise extension and retraction of the landing gear without stalling. Cost-effectiveness was also a key consideration, as traditional motor solutions were often too bulky, lacked the necessary torque-to-size ratio for the demanding application, or were too expensive for the project’s budget. Achieving this critical balance of performance, size, and economic viability was paramount for the safety and efficiency of the aircraft.
The ISL Products Solution: PGM-38P-12-51-392-CBB
In response to these stringent aerospace requirements, ISL Products International identified the PGM-38P-12-51-392-CBB (MOT-I-81508-38-51) as the optimal solution. This high-quality Ø38mm Brushed Planetary Gear Motor was precisely engineered to address the customer’s multifaceted challenges, offering a blend of compact design, robust performance, and economic viability perfectly suited for critical linear actuation.
Key Features and Benefits of the PGM-38P-12-51-392-CBB
The selection of the PGM-38P-12-51-392-CBB was predicated on several key attributes that directly corresponded to the linear actuator’s critical needs:
- Compact Size for Seamless Integration: A defining characteristic of this motor is its compact dimensions. Measuring a mere 38mm in diameter and 115.5mm in overall length, the PGM-38P-12-51-392-CBB was perfectly suited for integration into the space-constrained design of the linear actuator system within the aircraft’s structure. This compact form factor was essential for maintaining the small footprint required for the landing gear mechanism, a crucial design objective for the aircraft manufacturer.
- Robust Torque Output for Demanding Loads: Operating on a 12VDC voltage, the motor boasts a rated torque of 20 kg.cm at a rated speed of 351 rpm. Critically, it exhibits a high stall torque capability, reaching up to 185 kg.cm with a stall current of 110A. This significant power reserve is vital for handling heavy loads and overcoming initial inertia during landing gear deployment and retraction without stalling. Brushed DC motors, like the PGM-38P-12-51-392-CBB, are known for their potential to supply three to four times, or even up to five times, their rated torque without stalling, providing ample power for demanding tasks. It is important to note the gearbox limitation, which is set to 75 kg.cm for continuous operation to ensure longevity, though the gearmotor assembly can handle momentary peak torques up to approximately 100 kg.cm.
- Planetary Gearhead for Precision and Efficiency: The integrated planetary gearhead was a pivotal factor in the motor’s suitability. This gearhead type is renowned for its exceptional torque multiplication and high efficiency, making it ideal for applications demanding precise control and positioning, such as the controlled movement of landing gear. Its compact design further supports space-constrained installations. Moreover, the planetary gearhead ensures smooth operation by significantly reducing vibrations and noise, which directly contributes to the overall performance and accuracy of the linear actuator system.
- Cost-Effective and Reliable Performance: As a brushed type motor, the PGM-38P-12-51-392-CBB offered a cost-effective solution without compromising on the required performance, aligning seamlessly with the project’s budget. Its high-quality construction is designed to ensure a long operational lifespan and reliable performance, thereby minimizing downtime and reducing maintenance needs. While brushed DC motors may have a shorter life span when compared to brushless counterparts, their initial affordability and robust performance for specific applications often present a compelling value proposition.
- Optimized for Intermittent Duty: This motor is specifically best suited for intermittent duty operation. This characteristic made it an ideal choice for tasks that do not necessitate continuous high-load running, such such as the periodic deployment and retraction cycles of aircraft landing gear. This design optimization further enhances its lifespan and reliability within such application profiles.

The PGM-38P-12-51-392-CBB proved transformative for the aircraft’s linear actuator system. It successfully met the stringent requirements for precise speed control and delivered robust torque, even under dynamic and varying load conditions during landing gear operation. The motor’s inherent ability to provide high starting torque and maintain performance without stalling enabled seamless and highly accurate extension and retraction. This directly translated into improved operational efficiency and safety for the aircraft, ensuring that the landing gear could be deployed and stowed with consistent accuracy and optimal speed, thereby enhancing overall flight performance and reliability.
Optimized Design: Maximizing Space Efficiency and System Elegance
The motor’s compact size, with its Ø38mm diameter and 115.5mm overall length, was a pivotal factor in enabling a highly elegant and efficient mechanical design for the linear actuator system. This allowed the customer to successfully maintain the desired small footprint for their landing gear unit, which was a critical design objective for integration into the aircraft’s structure. The compact design not only minimized the overall system size but also contributed to reduced weight and increased flexibility in aircraft design.
Cost Efficiency: Delivering Value Beyond the Initial Investment
The PGM-38P-12-51-392-CBB, leveraging its brushed DC motor technology, offered a remarkably inexpensive startup cost, which significantly contributed to meeting the project’s financial objectives. In a sophisticated B2B context, the understanding of “cost-effectiveness” extends beyond the initial purchase price to encompass the Total Cost of Ownership (TCO) relative to the achieved performance and, crucially, the suitability for the specific application over its operational lifespan. For this particular intermittent duty application, the PGM-38P-12-51-392-CBB offered a compelling and genuinely cost-effective TCO. The lower upfront cost directly addressed immediate budget constraints. Critically, the “intermittent duty” design mitigates the typical concerns regarding “shorter lifespan” and “higher maintenance” associated with brushed motors because the motor is not subjected to continuous, high-stress operation. This means the customer received the required high performance and precision at an optimal price point for their specific use case, without incurring unexpected failures or excessive, unscheduled maintenance. This nuanced understanding of value positions ISL as a strategic partner who not only supplies components but also deeply understands the economic realities and operational demands of their customers’ applications.
