Section 1 General Information Overview This manual contains general procedures that apply to Baldor Linear Motor products. Be sure to read and understand the Safety Notice statements in this manual. For your protection, do not install, operate or attempt to perform maintenance procedures until you understand the Warning and Caution statements. A Warning statement indicates a condition that can cause harm to personnel. A Caution statement indicates a condition that can cause damage to equipment.
Safety Notice: This equipment contains high voltage! Electrical shock can cause serious or fatal injury. Only qualified personnel should attempt installation, operation and maintenance of electrical equipment. Be sure that you are completely familiar with NEMA publication MG-2, safety standards for construction and guide for selection, installation and use of electric motors and generators, the National Electrical Code and local codes and practices.
Receiving Each Baldor motor is thoroughly tested at the factory and carefully packaged for shipment. When you receive your motor, there are several things you should do immediately. 1. Observe the condition of the shipping container and report any damage immediately to the commercial carrier that delivered your motor. 2. Verify that the part number of the motor you received is the same as the part number listed on your purchase order.

Section 2 Installation & Operation Overview Installation should conform to the National Electrical Code as well as local codes and practices. When other devices are coupled to the motor, be sure to install protective devices to prevent accidents. Machinery that is accessible to personnel should provide protection in the form of guard rails, screening, warning signs etc.
LMAC Linear Induction Motor General Description: Single or three phase, linear AC induction motor primary. Construction: Epoxy encapsulated and steel laminated coil assembly (motor primary) Motor secondary (customer supplied) must conform to the following specifications: 1/8–inch aluminum or copper plate backed by a 1/4 inch cold rolled steel plate. The width of the secondary must be at least the with of the motor coil assembly.
LMBR Series Brush DC Linear Servo Motor Mounting The motor primary must be aligned (parallel) to the equipment guide ways within 0.005″ (0.127mm) on each end. Use gauge blocks and shims as necessary. Precise parallel alignment of the motor to the equipment guideways is required. Align the stationary half of the motor to the guideways. Then align the moving half with the stationary half. When securing the primary to the equipment base do not allow the screws to penetrate the motor more than .
LMBL Series Brushless Linear Iron Core Servo Motor Installation Refer to Figure 2-1. 1. Install the magnet assembly onto the machine mounting base. 2. With the slide assembly removed from the rails, install the coil assembly onto the slide, tightening the mounting screws. 3. Place a non–magnetic shim over the magnets, sized to cover all the magnets. (The shim thickness must be equivalent to the air gap specification. The normal air gap is 0.030″ ± 0.005″ unless otherwise specified). 4.
LMBL Series Continued Brushless Linear Iron Core Servo Motor Continued Multiple Coil Assembly Operation In addition to maintaining an air gap, multiple coil assemblies must also maintain a spacing factor of 1.8″. In other words, the space between coil assemblies may vary, however, the distance from the front end of the first coil assembly to the front end of the next must be a multiple of 1.8″. See Figure 2-2. Ensure that this spacing is established at the time of installation.
LMBL Series Continued Brushless Linear Iron Core Servo Motor Modular Magnet Track Installation Continued Refer to Figure 2-3. Some magnets are provided in modular segments. This is the recommended procedure to install these modular magnet track sections. Note: It is recommended that rubber coated tool handles be used to reduce injury (pinching fingers etc.) and protect the surface of the magnets. 1. 2. Bolt the coil assembly onto the underside of the slide (carriage).
LMBL Series Continued Brushless Linear Iron Core Servo Motor Modular Magnet Track Continued Continued 4. Install the remaining magnet track sections on the base plate. See Figure 2-5. 5. Remove the air–gap setting shim from the magnet track before use. Figure 2-5 Modular Magnet Track Installation Install other section of magnet track with slide positioned as shown Guide Rail Operation Considerations The motor must always be operated within the specified operating parameter limits.
LMCF Series Brushless Linear Cog Free Servo Motor 1. Install the coil and magnet assemblies. While mounting the coil, be sure to adjust coil assembly so it is centered within the magnet assembly with equal air gap in the vertical and horizontal positions. See Figure 2-6. 2. Verify that the coil assembly is centered within the magnet assembly with equal air gap in the vertical and horizontal positions along its entire length of travel.

LMPY Series Polynoid Linear Motor Holding Option Mounting: Switching: The rectifier package is wired externally in the stator circuit. For 115/60Hz, rectifier package CO0126A00 is provided. For 230/60Hz, rectifier package CO0125A00 is provided. Rated holding force is only achieved when the keeper plate is against the holding coil. To reduce shock loads, a shock absorbing connection between the polynoid rod and the load is recommended. Two switching modes can be used for various applications.
LMPY Series Continued Polynoid Linear Motor Holding Option Continued Operation Considerations The motor must always be operated within the specified operating parameter limits. Exceeding those limits will permanently damage the motor. Note: Rod should not support axial loads that can induce premature bearing failure. The following steps must be completed to ensure safe and proper operation. 1. Verify that all electrical wiring and cables are properly connected.

Bearing Maintenance Recirculating Bearing Rail And Block Lubrication type: For grease lubrication, a lithium–soap base grease (consistency No. 2 of JIS) is most frequently used. For linear guides operating under a heavy load, a grease containing extreme pressure additive is recommended. Maintenance procedure: Clean rails with clean cloth. Apply a thin film of grease onto the rail.
Encoder Maintenance RSF Series MSA6x Enclosed Type Technical Data: Linear encoders measure the position of linear axis without mechanical translation components. This reduces the potential error due to thermal behavior of the linear motor and backlash from mechanical translation. Encoder type: Non contact optical, sealed type.
RSF Series MS6x Open Type Glass Scale Encoder type: Non contact optical, glass scale, open type. Open scale linear encoders are used primarily where environmental conditions are clean, dry and free of oils. Due to the fragile nature of the encoder scale, extra care should be taken to prevent physical damage from impact or abrasion. Mechanical design: Glass scale, optical scanning unit, high flex twisted shielded cable. Encoder is adhered to stage surface with a two part, releasable bonding agent.
Renishaw RGH22 series Open Type Metal Scale Encoder type: Non contact optical, metal scale, open type. Open scale linear encoders are used primarily where environmental conditions are clean, dry and free of oils. Due to the fragile nature of the encoder scale, extra care should be taken to prevent physical damage from impact or abrasion. Mechanical design: Metal scale, optical scanning unit, high flex twisted shielded cable. Encoder is adhered to stage surface with a two part, releasable bonding agent.
Renishaw RGH22 series Open Type Metal Scale Continued Specifications: DC Power: 5VDC @ 120mA Output Signal: Square wave differential line driver to EIA RS422 (except limit switch Q and external set–up signal X).

Cables and Cable Chain Procedures If your positioning stage is supplied with a cable chain, follow these recommendations regarding its use: S Your stage is supplied with high flex cables that are designed to withstand millions of bend cycles. In addition, the internal conductors of the cable are twisted and shielded. A twisted, shielded cable reduces the problems associated with EMI and EFI noise. Using other types of cable may cause difficultly during servo tune procedure.
