Imaginary process of unrolling a rotary motor.
A variation of the linear motor is the tubular linear motor. This design rolls up the motor about an axis parallel to its length. This results in a “noncommutated” motor. Designs are available with either a moving coil or moving magnets.

Linear Motors are Designed for High Linear Velocities and High Acceleration

Baldor has a wide variety of linear motors, positioning stages and controls for your application needs. They provide direct linear motion without mechanical linkages, therefore no backlash. Standard and custom designs are available. Baldor also has drives and motion controllers for powering and positioning of linear motors and stages.
Advantages of Linear Motors
• High speeds – 200 in/sec [5 m/s] with encoder resolution > 1 micron
• High accelerations – up to 10 g’s [98 m/s] • Small, compact – fits into smaller spaces • Unlimited strokes from 0.01 in [0.000254 m] • Submicron positioning when coupled with appropriate
Tubular non-commutated DC Linear Motor.
Linear Motor Performance
Linear motor output is measured in Lbs. [N] of force or thrust:
• Linear motors provide force to 2000 Lbs. [8900N], and speeds to 200 in/sec [5 m/s] depending upon encoder resolution.

The same electromagnetic force that produces torque in a rotary motor also produces direct force in a linear motor. For example, a permanent magnet DC linear motor is similar to a permanent magnet DC rotary motor and an AC induction linear motor is similar to a squirrel cage induction motor.
Take a rotary motor, split it radially along its axis of rotation and flatten it out. The result is a flat linear motor that produces direct linear force instead of torque. Why? Torque is force at a distance. Removing the distance (axis of rotation) leaves direct linear force. It follows that linear motors utilize the same controls as rotary motors. And similar to a rotary motor with rotary encoders, linear motor positioning is provided by a linear encoder.
