DC
Brushed Linear Servo Motor – LMBR series
The brushed linear motor is designed for long stoke self-commutated servo
applications. The “platen” contains multiple coils (turns of wire) inserted
into insulated slots along with a commutator bar. The “forcer” features
multiple permanent magnets and brushes for commutation. It is used with pulse
width modulated (PWM) DC servo controls. The LMBR series provides high peak
forces of 1070N (171 lbs); speeds to 3.8 m/sec (75 in/sec); and acceleration
to 5 G’s.
Polynoid
Linear Motor
The AC polynoid linear motor derives its name from the solenoid - it
provides strokes with constant force over a short limited distance. These are
induction motors, which consists of a copper clad “rod” and a “stator”.
Forces provided up to 240N (54 lbs).
Non-Commutated
DC Linear Motor
The non-commutated linear motor provides strokes with constant force over a
short limited distance. These are DC linear motors available as either moving
magnets or moving coils. Peak forces provided up to 670 N (150 lbs).
