More Info

Capable of 4KW, the 3220 is the largest motor in the 32XX line. The 3220 also comes with the option of a 1/2" diameter shaft and large diameter bearings for increased durability. The 3220 weighs approximately 4 lbs.

Superior Quality


The goal with the 32XX has been to create a superior quality motor. Starting at the core of the motor, the 32XX 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 32XX motors are designed and manufactured in Astro Flight's facility in Irvine, CA. The design, high quality materials, and manufacturing precision allows the 32XX motors to have a power-to-weight ratio two to the three times that of its competition.

Support and Customization


One of the key features that makes AstroFlight unique is its ability to tailor motors to customers' needs. Since the 32XX 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.

Quiet and Efficient Performance


The 32XX'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.

All these factors allow the 32XX motors to achieve a peak efficiency as high as 94%. Furthermore, the motors maintain their high efficiency over a wide range of voltage and current values. This makes the 32XX flexible in customers' systems.

One may use a high voltage controller like the Castle Creations HV85 or HV110.

 

CUSTOM OPTIONS FOR THE 3220

Shaft Diameter

The standard 3220 shaft is 3/8" in diameter. We also offer a 1/2" version which includes larger diameter bearings for less rolling resistance.

Shaft Length

The standard 3220 has 1.8" of the 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.

Temperature Sensor

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).

Ported Housing

The standard 3220 has a sealed can to protect against environmental elements like dust and dirt. However, we also offer a ported housing option that has large cut-aways in the front and rear faces of the motor to allow better convective cooling of the end turns.
