An aerospace electric motor requires a design and series of components that can endure tough operational demands. The motors must perform reliably and safely, as applications on and around air spacecraft are considered critical.
Aerospace motors are often subjected to extremely high and low temperatures, as well as moisture and pressure fluctuations, and a number of other factors. As a result, they are specifically made to operate even as these conditions change and/or reach extremes.
In addition to safety and endurance, weight can be an important consideration for some aerospace motors. Parts will often need to be made of strong but lightweight materials to meet the requirements of some air and spacecraft.
Aerospace military motors are used in a range of air, sea, and land defense applications. They must be designed and built to meticulous performance standards. In many cases, custom aerospace military motors are utilized so that each motor will suit the individual parameters of a specific piece of equipment or overall system.
Aerospace and military motors can also include fairly standard types of motors, including AC brake and induction motors, 400 Hz motors, and servo motors that are simply made with mil-spec materials. High-performance housing, insulation, writing, and other parts are often required.
The addition of gearheads, electronic or tachometer feedback, integral breaks, and other features is easy when motors are sourced directly from an aerospace motor manufacturer. Working directly with the producer of the motor will allow for more freedom and control over the end product.
What Makes A Motor An Aerospace Motor?
An aerospace motor is used for a range of motion control functions, but it is specifically designed to satisfy the safety, weight, performance, and other requirements of the aerospace and defense industries. Aerospace motors must be designed to operate in extreme and fluctuating conditions, including high and low temperatures and varying pressure changes. Their design and parts must all be catered to these application requirements.
What Are Different Types Of Aerospace Motors?
Many different types of motors that can be used as aerospace motors, including AC induction motors, AC brake motors, servo motors, brushless DC (BLDC) motors, and hysteresis synchronous motors. What makes the motors suitable for use as an aerospace option is their higher frequency operation, compact size, high-temperature components and insulation, and precision designs.
What Are Aerospace Motors Made With?
Aerospace motors are typically made with high-energy magnetic materials, high-temperature Class H insulation, special sealing, and housing that is all rated high performance or high temperature. Individual components must also be lightweight and highly reliable.
Why Are 400 HZ Motors Ssed In Aircraft?
400 Hz alternating current (AC) motors are more frequently used in aircraft, spacecraft, and in many marine applications because they are lighter and more compact than 50 or 60 Hz. The magnetic core of a 400 Hz motor allows for comparable power level in a more compact structure. The higher frequency of this type of motor is also conducive to maintaining a power system within a smaller space, including land, air, space, and sea vessels.
Why Aren’t 60 HZ Motors Used In Aerospace Applications?
60 Hz motors are used in many standard and industrial appliance applications, but they are typically considered too large and heavy for many precision aerospace settings. Lighter weight, more compact 400 Hz motors are generally the preferred option for aircraft, spacecraft, and marine vessels.
Where Can I Get Frameless Aerospace Motors?
Frameless aerospace motors can be sourced from some aerospace motor manufacturers. The absence of a frame allows for more versatile fitting to custom equipment and parts.
