Slotless brushless DC motors have found a very wide range of applications in the defense and aerospace industries worldwide. Thanks to their compact structure, these motors have long been used in demanding projects where every gram is crucial. Offering many advantages over traditional slotted stator structures, slotless brushless motor designs provide negligible magnetic revving, improved servo performance, and flawless motion even at low speeds. Low inductance and high current bandwidth result in fast motion response times. The slotless structure also provides excellent winding heat transfer for high thermal efficiency and transient load capacity. FEMSAN, having started its project to create a family of slotless brushless DC servo motors in 2014, completed this project with a completely original design from A to Z, thus freeing our domestic defense industry from external dependence in this field. Slotless brushless DC motors, which are almost indispensable for the wing drive systems of ammunition, can only be produced in countries that have reached a certain level of technology. In the slotless brushless DC motor market, FEMSAN, which currently produces motors with diameters between 25-40 mm, aims to add products with diameters of 16 and 12 mm to this motor family in the short term.
FEMSAN: The Address for Wing Drive Systems and Linear Actuators
Wing actuation systems are complex subsystems used to change the position of the wings of missiles and other platforms in accordance with guidance commands from the flight computer. A typical missile wing control actuation system consists of four actuators that are compatible with and integrated into the missile's outer fuselage line. FEMSAN can provide complete production and related engineering services for optional electromechanical control actuation systems for guiding missile wing position.
Linear actuators are preferred in wing propulsion systems of smart munitions, missiles, and similar structures where volume and weight parameters are extremely critical. FEMSAN also produces linear actuators for precision guidance kits. For this purpose, a ball screw or transmission screw/nut is mounted on a grooveless or coreless brushless DC motor to convert rotary motion into linear motion. FEMSAN linear actuators, which are highly precise motion sources for wing propulsion systems, meet military standards in challenging environments.
FEMSAN Develops Rotary and Linear Servo Actuators for UAVs
FEMSAN, which possesses the capability to design and manufacture electromechanical actuators, is very close to extending its success in this field to the skies. To drive various subsystems on UAVs, FEMSAN has designed and developed both rotary and linear actuators. Having produced the first prototypes and continuing the necessary work for qualification, the company designs and manufactures not only servo actuators but also alternators for UAVs. With its technological advancements, FEMSAN is also making moves to meet the alternator requirements of unmanned aerial vehicles, whose use is becoming increasingly widespread.
