Motor Overview
Overview
Motors are devices that convert electrical energy into mechanical motion. In FRC robotics, motors are the powerhouse that make everything move - from driving the robot around the field to operating mechanisms like arms, shooters, and intakes.
Types of Electric Motors
Brushed Motors (The Older Type)
Think of it like:
- Something inside physically "switches" the electricity as it spins. Like little contacts rubbing.
Good parts:
- Usually cheaper to make and buy. Simple.
Not-so-good parts:
- Those rubbing contacts wear out over time, like pencil erasers. This means they don't last as long, create some friction (which wastes a little power and makes heat), and can be a bit noisy or sparky.
FRC legal motors:
- CIM, Mini CIM, Bag, 775 pro, Venom
Brushless Motors (The Newer Type)
Think of it like:
- The switching of electricity is done electronically, with smart parts, instead of physically rubbing.
Good parts:
- Last much, much longer because there's no rubbing to wear things out. More efficient (use less power to do the same work). Often more powerful and smoother.
Not-so-good parts:
- Cost a bit more upfront because they need those smart electronic parts.
FRC legal motors:
- Falcon, Kraken 60x, Kraken 44x, Neo
Motor Controller
Think of a motor controller as the brain for an electric motor. Instead of just turning a motor on or off at full power like a simple switch, a motor controller lets you control it.
Types of Motor Controllers
There are typically two main ways motor controllers work:
Integrated Controllers:
- The controller is built right into the motor
- Examples: Falcon 500, Kraken motors
Non-Integrated (External) Controllers:
- The controller is a separate unit connected by wires
- Examples: Talon SRX, Spark MAX, Victor SPX
