DON'T BE FOOLED BY VOLTAGE!! Comparing a brushless motor to a brush motor is like comparing a sports car to a regular car. You can put high octane fuel in a regular car but it still won't outperform the sports car. |
| Motor |
Brush with switch |
Brushless with controller |
More efficient and flexible technology. Many of the limitations of a classic Brush DC Motor are due to the need for brushes to press against the commutator. |
| Efficiency |
Regular Brush |
Brushless |
Approx. 20% or more efficient. Brushes have difficulty maintaining contact at higher speeds and may bounce off irregularities in the commutator surface, creating sparks. This limits maximum speed in brush machines. |
Run Time
per charge
|
Affected by brush friction |
Brushless |
Longer run times—Approx. 20% more efficient. |
Speed/RPM's
per charge |
Fixed |
Variable—microchip will control depending on cut and power required |
Has the ability to control motor speed. It provides more performance when required and conserves power when not required. |
| Batteries |
Unprotected |
Protected |
Ensures that batteries do not get over discharged and regulates the current draws protecting both the motor and the batteries therefore ensuring longer battery lifespan. |
Self
Diagnostics |
N/A |
Yes |
Just like a modern automobile, the Terra Phase Power System can diagnose itself. |
| Controller |
On/Off switch only |
Electronic controller manages acceleration, speed and fine tunes efficiency |
Adjusts motor output to the cutting conditions. Speeds can be maintained longer to mow through tough conditions. |
| Acoustic Noise |
Brush contacts make more noise |
Lower noise levels—less friction |
Eliminates the imperfect electric contacts found in brush motors that causes increased electrical noise. |
| Performance Environment |
Brush motor designs make it susceptible to humidity elevations, dust and debris. |
Completely sealed design protects from dirt and other foreign matter (i.e. can be pressure washed) |
Brushless motors require virtually no maintenance and maintain their performance over their lifespan. |
| Weight/Size |
Larger and heavier motor required for similar performance |
Smaller and lighter motor required for similar performance |
Brushless motors require less parts. |
| Maintenance |
Wear items include brushes and springs, cleaning, gearbox. Exposed to debris |
No wear items, fully sealed unit |
No maintenance = customer satisfaction. |
| Lifespan |
Approx. 2,000 hours— although system can degrade quicker throughout lifespan |
Approx. 15,000+ hours. System will not degrade through use |
8x or greater motor lifespan. No brushes to wear out or require replacement, and the commutator itself is not subject to wear and maintenance. |
| Safety |
Heat and arcing |
Low heat and no arcing |
No arcing and heat damage increases the motor lifespan. |
| Over temperature protection |
N/A |
Yes |
The Terra Phase motor is equiped with a smart system that will stop the motor from overheating. |
