Baldor provides industry with the widest range of linear motors, linear stages and controls. Being a leader in linear motor design and manufacturing, Baldor continually develops advanced products and innovations to meet a variety of linear motion applications.
Linear motors provide unique speed and positioning performance advantages. Linear motors provide direct-coupled motion and eliminate mechanical transmission devices.
They offer substantial improvements over applications using ball screws, timing belts, etc. The rugged mechanical design provides accurate motion and precision positioning for hundreds of millions of cycles. Baldor linear motors and stages are used in thousands of successful applications worldwide.
The Cog-free brushless linear motor is designed for unlimited stroke (travel) servo applications that require smooth operation without cogging. These motors are supplied in kit form to be integrated into a customer's machine. They are used in closed-loop servo systems and provide optimum performance.
The linear brushless AC Cog-free servo motor consists of a stationary magnet track and a moving coil assembly. The U-shaped, multi-pole magnet track is comprised of alternating polarity rare-earth magnets bonded to a hardchrome plated, cold-rolled steel plate. Modular track assemblies stack end to end to provide the length of stroke required. The coil assembly must be centered within the U-shaped magnet track and guided by customer supplied bearings. Individual coil assemblies can be mounted in series (as a single unit) to increase force. Multiple coil assemblies having independent operation and overlapping trajectories can also be mounted on a single
Baldor introduces the newest Linear Iron Core Brushless Servo Motor designed with advanced technologies to minimize cogging, while improving dynamic speed and acceleration capability.
The new LMIC motor series has been uniquely designed, without magnet skewing or slotting, to minimize cogging force thus providing applications with the smoothest possible operation.
Baldor has redefined linear motors with a technological breakthrough. Baldor's new HyCore motor combines the best features and performance of traditional high speed, high force, closed loop brushless linear servo motors, with the cost advantages of open loop linear stepper motor technology. HyCore includes many benefits, which linear motors bring to an application: zero backlash; high efficiency; unlimited travel; fast velocities and high accelerations.
The Brushed Linear Servo Motor is designed for long stroke servo applications. It is ideal for direct linear motion without mechanical linkages in closed-loop position packages.
The moving permanent magnet brush commutated DC linear motor consists of a stationary primary and a moving secondary. The stationary primary is a steel laminated core, with multiple coils inserted into insulated slots. The ends of each coil are connected to a commutator bar that is mounted on an aluminum angle.
The moving secondary features multiple permanent magnets and brushes for commutation. A cable supplies power to the moving secondary. Mounting holes are located on both the primary and secondary.
The magnetic-attractive force between the primary and secondary can be used as a magnetic preload for the bearing system. The customer-supplied bearing system must maintain an air gap of 0.064 cm [0.025 inch] between the primary and secondary. The brush linear motor is available in different cross sections to meet different force requirements.
The Linear Induction Motor (LIM) is designed for highforce, long-stroke applications, such as material handling and people movers.
A variable frequency inverter will provide velocity control of a linear induction motor. A Linear Induction Motor (LIM) equipped with a linear encoder can do point to point programmable positioning when driven with a vector control and motion controller. These motors are supplied in kit form with customer providing reaction plate (secondary) and bearing system to be integrated into the application.
The open-loop linear stepper motor provides the most economical linear motor positioning package. The compact dual-axis stepper motor provides travel along two axes in a single plane.The dual axis package is comprised of two components: a moving forcer (with bearings) and a stationary platen. A position verification system is available to close the loop.
The dual-axis linear stepper motor is designed for two-axis open loop positioning. It is a two axis stage with integrated air bearings and positioning system.
The moving primary 2 or 4-phase dual-axis linear stepper motor consists of a moving forcer and a stationary platen. The forcer is made of four single-axis coil assemblies. Two of the forcer assemblies are mounted in series to provide a thrust in the X direction and the other two are mounted orthogonal (at 90 deg.) to the first two assemblies to provide thrust in the Y direction. The forcer assemblies are encapsulated in a hard anodized aluminum housing. The motor's surface is lapped to provide a flat surface for the air bearing. The floating height of the air bearing is less than 25 m [0.001 in]. The forcer is available in eight sizes, depending on the application's
The platen is a photo-chemically etched steel plate that is filled with epoxy and ground. Standard mounting holes are provided on forcer and platen. The platen is available in sizes up to 0.24m x 0.34m [36 in x 59 in]. Preload for the bearing system is provided by the magnetic-attractive force between the forcer and the platen. The customer must bring power to the forcer with a cable, and provide the bearing air supply.
