EV3 Motors

Large Motor

The Large Motor is a powerful "smart" motor. It has a built-in Rotation

Sensor with 1-degree resolution for precise control. The Large Motor

is optimized to be the driving base on your robots.

By using the Move Steering or Move Tank programming block

in the EV3 Software, the Large Motors will coordinate the action

simultaneously.

Medium Motor

The Medium Motor also includes a built-in Rotation Sensor (with

1-degree resolution), but it is smaller and lighter than the Large

Motor. That means it is able to respond more quickly than the Large

Motor.

The Medium Motor can be programmed to turn on or oﬀ, control its

power level, or to run for a speciﬁed amount of time or rotations.

COMPARE THE TWO MOTORS:

The Large Motor runs at 160–170 rpm, with a running torque of

20 Ncm and a stall torque of 40 Ncm (slower, but stronger).

The Medium Motor runs at 240–250 rpm, with a running torque

of 8 Ncm and a stall torque of 12 Ncm (faster, but less powerful).

Both motors are Auto ID supported.

For more information on using the Rotation Sensor in your

programming, see Using the Motor Rotation Sensor in the EV3

Software Help.
