1. Product Introduction
Linear motors can be positioned extremely accurately by using optical encoders and rulers. If this is not required
this expensive setup can be replaced by an Analog Hall module. This module uses the magnet track, as opposed to
the ruler, as the linear scale. It can be easily mounted on our iron core motors and communicates with
practically all standard servo controllers. The Analog Hall module requires a standard 5Vdc power supply.
For commutation, we have an optional digital Hall module that can be used with our entire range of linear motors. Its
sensors provide 3 digital outputs, each phase shifted 120 degrees, to determine the electrical angle between
coils and magnets. If you do not use a controller that allows you to commutate within the servo drive, this
module can be a cost-effective alternative. The digital Hall module requires a 4.5 to 28Vdc power supply.
2. Product Parameter (specification)
3. Product feature and application：
A linear motor could be thought of as rotary electric motor that has been cut along a radial plane and unrolled. The
resultant linear servo motor is an electromagnetic direct drive linear motor that can produce linear motion
electrically and without contacting parts, eliminating backlash, windup, wear, and maintenance issues. Linear
motion is generated without the need of pneumatic, hydraulic cylinders, or translation of rotary to linear
motion with the use of gearboxes, spindles, belts, rack and pinion, or screws.
Linear motors are
currently used inside robots, actuators, precision tables/stages, fiberoptics and photonics alignment and
positioning, assembly, pick and place systems, machine tools, semiconductor equipment, electronic manufacturing,
inspection systems requiring responsive control at high bandwidths, vision systems, and in many other industrial
motion control applications.

6. Deliver, shipping and serving:
DC brushless linear motors provide non-contact operation for maintenance-free operation. Available in both ironless
(cog-free) and iron core versions. They are capable of high speed and high acceleration motion profiles. They
can be driven using standard 3 phase brushless servo amplifiers. Brushless linear motors can achieve an
acceleration of up to 12 g’s, and speeds in excess of 200+ inches per second [5+ m/s].
DC brush linear motors are ideal for long stroke, open or closed loop servo, linear motion applications. They can be
used at speeds up to 100 in/sec [2.5 m/sec] and as low as 1 in/sec [25 mm/sec]. They are capable of very precise
position, velocity, and acceleration control when coupled with a linear encoder.
DC voice coil actuators are ideal for short stroke (typically less than 2 inches) closed loop servo applications.
Their compact size allows them to fit into small spaces. They have very low electrical and mechanical time
constants. The low moving mass allows for high accelerations of light payloads. They are available in both
moving coil and moving magnet versions.
Linear stepper motors are used in both open loop and closed loop positioning applications. Since the positioning is
built into the forcer and platen, no additional feedback devices are required which reduces the overall cost of
a system. For open loop operation, no servo tuning is necessary. Multiple forcers can operate on a single
platen. With linear steppers, acceleration of 1 g and speeds up to 100 in/sec [2.5 m/s] are typical. They are
available in both single-axis and dual-axis versions.
The flat AC linear induction motor (LIM) is typically run directly off of 3 phase line voltage, with an adjustable
frequency, or vector drive if speed control is required. Accelerations of up to 1 g with speeds in excess of
1800 inches per second [45 m/s] are possible with LIMs. They are ideal for high speed, long travel applications
moving heavy payloads.
The tubular AC linear induction motor (polynoid) is typically run directly off of single or 3 phase line voltage.
Accelerations greater than 1 g are possible with polynoids. They are ideal for short stroke, low duty cycle
applications. They can be used to replace air cylinders when compressed air is not available.
