P4501 2816-940kV Brushless Motor from Tomcat - DY-TC-P-2816-KV940

Striking the ultimate balance of precision, performance, and price, Tomcat motors deliver features often reserved for much more expensive brands. Experience Tomcat's premium quality across a versatile range of equivalent motor sizes from sub-micro to 150cc!

Tomcat's renowned reliability begins with a rigorous production process. Each motor's primary components are CNC machined from solid blocks of aluminum alloy to achieve strict tolerances, instead of being cast from cheaper, imprecise molds. The stator is machine wound using premium wire and Japanese magnets that are especially resistant to high temperature conditions. Throughout these processes, inspections conducted at each station ensure consistently high quality.

All Tomcat motors include a comprehensive set of mounting hardware, tools, X-plate mount and compression collets in addition to the bolt-on propeller collet.  If you are looking for a reliable equivalent size brushless motor for your park flyer-size aircraft that you can trust, the Tomcat P4501 is your solution.

Features:

  • CNC-machined aluminum alloy body for high-end precision and tight tolerances
  • High quality Japanese bearings for smooth, low-heat operation even at high speeds
  • N45H magnets for superior heat dissipation and degaussing resistance
  • Dynamically balanced at the factory to eliminate vibration and extend motor life
  • All necessary mounting hardware is included

Includes:

  • Tomcat P4501 2816-940kV Brushless Motor
  • Bolt-on propeller adapter with 4mm shaft diameter
  • Mounting hardware
  • X-plate mount
  • Compression collets
  • Bolt-on propeller collet

tomcat motor Japanese bearing

All Tomcat motors are outfitted with the highest quality Japanese bearings, providing smooth operation and extending motor life.

The Tomcat motor's housing is specially designed to dissipate heat, which allows for continuous high output without over-heating.


Each Tomcat motor is dynamically balanced at the factory which means the motor will have minimal vibration and run quieter even at the highest rotation speeds.

Tomcat motors use premium N45H magnets which resist degaussing, even at very high temperatures, and allow consistent, powerful torque through the entire power band.

Tomcat motors are made of high-strength aluminum alloy which is impact resistant and improves overall heat dissipation.


Each housing is cut from a single block of aluminum using robotic CNC machines for precision and tight tolerances.

The motor magnet wire uses a special vacuum impregnation treatment process allowing it to resist heat up to 240°C. This heat-resistant design helps to prolong the service life of the motor.

Tomcat 4501 brushless motor

Havent flown it yet but great service and speedy delievery seems to be putting out lots of power only complaint is the prop adapter will not go on the motor shaft no hole drilled in it to allow the adapter to fit on the shaft have to drill it out or cut the shaft tricky to do as it is aluminum and the threaded part is not long enough to put the prop and spinner on.

Tomcat P4501 2816-940kV BL Motor

This motor is exactly what I need for my E-Lady. Good power, vertical climbs and dependable. For a mid-priced 28mm can it is a good value. If you need a 400 size motor that will pull 28-25 ounces this is a good bet for your money.

Good motor for good price

This motor does everything the manufacturer claims. I have one in a “Gentle Lady” two meter sail[plane converted to power. The whole set up weighs 28 ounces and goes up in a vertical clim using an 800 ma battery. I get a minimum of 5 climbs to 150 metres on one charge plus the 5 to 10 minute flights. Great buy
