Understanding and Caring for Your Linear Motor Anorad linear motors require no maintenance when operated in a relatively Maintenance clean environment. For operation in harsh and dirty environments, minimal cleaning is recommended every 6 months. Clean the metallic debris and other contaminants from the air gap. To effectively remove the metal debris use a strip of masking tape.
Chapter Installation Use the following section to guide you through installation and start-up of Introduction your LZ linear motor. Topic Page Unpacking and Inspection Installing the Linear Motor Motor Power and Feedback Cable Signal Names Motor-Hall Phasing and Sequence Positive Motor Direction Motor Coil Thermal Protection Operational Guidelines Inspect motor assemblies for damage that may have occurred in shipment.
Installation Use the following procedures to install the magnet channel and the motor coil Installing the Linear Motor to create a linear motor. Mount the Magnet Channel The required tools are: • magnet channel alignment tool (supplied). • aluminum straight edge. •...

Installation 3. Verify that the mounting configuration for the magnet channel and coil fits in envelope dimensions shown in diagram. Mounting Configuration A Mounting Configuration B Mounting Configuration C 0.10 (.003) 0.83 ± 0.40 (0.033 ± 0.015) Catalog Number mm (in.) LZM-030- 80.0 (3.15) LZM-050-...
Installation 4. Install the first magnet channel using M6 SHCS for mounting configuration A, or M5 SHCS for mounting configuration B and C. Non-magnetic tools and hardware such as beryllium copper, 300 series stainless steel, and others should be used. If not available, proceed carefully since magnetic and ferrous items will be attracted to the magnet channel.
Installation Mount the Motor Coil Follow these procedures to mount the motor coil to your machine slide. 1. Be sure the motor coil mounting face is clean and free of burrs. 2. Position the slide at the end of travel where the cable is to exit. 3.

Installation Disconnect the input power supply before installing or servicing ATTENTION the motor. The motor lead connections can short and cause damage or injury if not well secured and insulated. Insulate the connections, equal to or better than the insulation on the supply conductors.
Installation The LZ linear motor family is compatible with off-the-shelf brushless motor Motor-Hall Phasing and servo drives. The servo drive will see them as a two-pole motor with a full Sequence electrical cycle of 60 millimeters (360 degrees equivalent rotary motion). The brushless motor drives and controls must have two control functions for suitable commutation of a linear motor.
Installation Motor Phasing Diagram Back EMF Voltage vs. Hall Signals Back Voltage Digital Hall Signals 0° 60° 120° 180° 240° 300° 360° Linear Travel mm (in.) 60 (2.36) Phasing direction = the coil toward motor power cable for moving coil configuration as shown in Positive Motor Direction or the magnet assembly away from power cable for moving magnet configuration.
Installation Motor Coil Thermal Protection LZ linear motors with the thermal protection option will supply ATTENTION a signal that indicates the motor temperature limit condition. This signal should be used by the motor control or drive system to immediately shut down the motor power on an open condition.
Installation After installing the motor and before powering up your system for the first Operational Guidelines time, performed the Motor Coil Electrical Test on page 23 to verify motor condition. Moving parts can injure. Before running the motor, make sure ATTENTION all components are secure and the magnet mounting hardware is below magnet surface.
Chapter Troubleshooting Use this section to diagnose the health of motor coil and the Hall effect Introduction module. Topic Page Hall Effect Module PTC Thermal Signal Motor Coil Electrical Test Motor Back EMF Tests Checking the Magnet Channel Butting Polarity Use the following procedures to troubleshoot the Hall effect module.
Troubleshooting 6. Check for the proper logic levels (approximately 0V = low, +V = high) and the sequence: S1 leads S2 leads S3 with approximately 120 electrical degree spacing in between. Connect the probe common to the Hall signal common. Hall to Back EMF Phasing 1.
Troubleshooting Perform this test after installation and when a coil electrical fault is suspected. Motor Coil Electrical Test Dangerous voltages, forces and energy levels exist in servo ATTENTION controlled systems. Extreme care must be exercised when operating, maintaining or servicing the linear motor to prevent harm to personnel or equipment 1.
Troubleshooting 7. Compare the phase resistance readings to the cold resistance specification of the specific coil model. The three reading should be about the same and comparable to the cold resistance specified for your model. When the coil is hot the resistance reading should still be balanced and but may be as mush as 30 …...
Troubleshooting 5. Repeat step 4 comparing V-W to U-W. In this case U-W should lead V-W by 60 . The shapes and peak voltages should be approximately the same. Note that probe common = W. Be sure to use the same phasing direction as in step 4.
Troubleshooting Mechanical displacement of one electrical cycle = motor magnetic pitch (180 in inches multiplied by two. Note that the published specification may already be in “cycles.” In this case do not multiply by two. Use the following equation to calculate back EMF constant: mechanical displacement of one cycle (in) ---- - ------------------------------------------------------------------------------------------------------...
Page 27
Troubleshooting 5. Using an oscilloscope, connect one channel between any Hall signal (output) and the Hall signal common. 6. Slowly and steadily move the motor by hand in one direction over the whole travel. Monitor the waveshape as you are doing this. The Hall signal should alternate between a high and low DC level of equal duty cycle (squarewave), as the Hall module passes over the alternating polarity magnets.
