The 40XX series motor is offered in 4 standard configurations, 4020, 4015, 4010, and 4005 with respect to four different motor core lengths. The 40XX comes with a 1/2" diameter shaft and large diameter bearings for increased durability, capable of 4KW, 3KW, 2KW, and 1KW.
The goal with the 40XX has been to create a superior quality motor. Starting at the core of the motor, the 40XX uses the highest grade of sintered samarium-cobalt magnet. This is a very high quality magnet that is rarely found on motors of this price point. Typically, manufacturers use neodymium or ferrite magnets to cut costs, but they tend to demagnetize in use. Astro Flight has chosen samarium-cobalt for its high magnetic strength, high-temperature capability and virtually zero demagnetization susceptibility. Around the magnetic rotor are high grade ultra-thin annealed stator laminations that ensure low eddy-current and hysteresis losses. To handle high continuous and burst power, every component from the epoxies to the wire insulation has been rated to at least 200°C. Finally, to ensure manufacturing quality, all 40XX motors are designed and manufactured in Astro Flight's facility in Irvine, CA. The design, high quality materials, and manufacturing precision allows the 40XX motors to have a power-to-weight ratio two times that of its competition. With its unique double-wall housing and built-in fan, no external cooling is needed.
Support and Customization
One of the key features that makes Astro Flight unique is its ability to tailor motors to customers' needs. Since the 40XX motors are built to order and manufactured in-house, customers can request different housings, cooling configurations, shafting, and turn count. The engineering team can assist customers with proper motor selection and customization options. Mounting holes or slots can be customer specified.
Quiet and Efficient Performance
The 40XX's stator design and magnetic topology has been designed to produce a very clean trapezoidal back EMF which nearly matches standard square-wave brushless controllers. This makes for nearly silent operation and prevents damage to the controller and power supply.
CUSTOM OPTIONS FOR THE 40XX
The standard 40XX shaft is 1/2" in diameter, which includes larger diameter bearings for less rolling resistance.
The standard 40XX has 1.8" of shaft protruding from the front face and flush on the back. Customers may specify the amount of shaft length protruding from both sides of the motor.
An optional temperature sensor may be installed into the motor. This temperature sensor is embedded in the coil windings and has a temperature range from -40 to 300 Celsius (-40°F to 572°F).
The standard 40XX has a sealed can to protect against environmental elements like dust, dirt, and rain. A double-walled housing and a built-in fan allows cooling of the motor without external heatsink coolings.
