A 3-phase AC voltage directly from the line, an adjustable frequency supply, or a vector drive can be used to drive the LIM. The LIMs can be supplied for single phase AC, but the result is a less efficient motor. All standard voltages are available; 220, 380, 400, 415, 460, 600 @ 50 / 60 Hz
The speed of the LIM is proportional to the input frequency (which can be variable) and the pole pitch of the lamination stack (which is fixed). Connecting directly to the AC line at 50 or 60 Hz will produce a constant linear speed. Using an adjustable frequency drive (or inverter) will allow speeds as slow as 6 in/sec [0.15 m/s] and as fast as 1800 in/sec [45 m/s] at 400 Hz.
There are thru holes in the angles of the coil assembly for mounting to the customers system.
Single or three phase, linear AC induction motor primary.
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.
Motor should be kept dry and relatively free of contamination. This motor is water resistant, not water proof. Avoid submersion. Avoid contact with petroleum–based solvents. Alcohol or soapy water can be used to remove contaminants.
Refer to catalog or outline drawing supplied with motor for mechanical dimensions and electrical specifications.
Your motor may be supplied with either base or foot mounting, refer to catalog or outline drawing supplied with motor for mounting details and hole dimensions. It is recommended that all available coil assembly mounting holes be utilized to properly secure the coil assembly. If the coil is in motion, the motor wires must be strain relieved. We recommend that the motor secondary be secured with 1/4inch fasteners on the left and right sides of the secondary, every four to six inches of its length. An air–gap of 1/8 inch is recommended. Refer to linear induction motor duty cycle–force–current curves in this booklet for information regarding the affects of air–cap size on motor performance.
For voltage and current specifications, refer to Catalog BR1800 or to documentation enclosed for custom motors. The 10 foot flying leads can be cut to remove excess length if required. Connectors are available; contact a Baldor representative for more information.
For single phase motors, refer to the table supplied with this booklet for capacitor selection.
