Description
LM-1 Linear Motor Trainer Educational Equipment Electronic Drives For AC/DC Motors

The Linear Motor Trainer mod LM-1 has been developed for teaching this special kind of electrical machines, that are becoming very important in automation systems.
TRAINING PROGRAM:
• The mechanical concept and their significance: the classical concepts for rotational motors: torque, RPM, angular speed and angular positioning against their dual concepts for the LM: force, linear speed, linear acceleration and linear positioning. The relative formulas that link these parameters among them.
• Types of LM: operational principles and technical comparison among them regarding specific applications.
• Constructional blocks of a LM system: power and control signals fl ow.
• Parameters to define a LM: mechanical and electrical parameters according to the specific application.
• The LM electronic drive: the complete system description: motor- drive- sensors- data logger.
• LM system connection and start up.
• The LM performance and measurements: measurements of the combined mechanical parameters (acceleration, speed, force and positioning) against the electrical parameters
(voltages, currents, power) with and without payload.

TECHNICAL SPECIFICATIONS:
The system includes two units (the Motor and the Controller), plus the accessories:
1- THE MOTOR
• Permanent magnet synchronous LM, including: the magnetic rod (dia. 25 mm). with 2 rod supports and sliding base for the forcer. Total rod lenght: 740 mm approx. Forcer free travel: 510 mm approx..
• Max stall force: 42 N approx @ 1.95 A (phases series connection).
• Force constant Kf: 22 / 11 N/A (series / parallel phases connections).
• Protection grade IP67. LOS
• Position feedback sensor, integrated with the forcer.
Differential sinus/cosinus analog output type. It is the position feedback for the controller.
• External position sensor: mounted on the rod support,. It is the input for the supplied software.
2- THE CONTROLLER PANEL
• “Table-top” unit, completely contained in a robust metal box with long antitilting legs.
• LSM complete digital controller, microprocessor base, with 3 nested control loops: position, speed and current / torque.
• With 2 potentiometers, one for setting the forcer position, the second for setting the speed.
• Two signaling LEDs.
• Four fi gures display, that works with a 3-positions rotative selector to show position, speed, and current.
• Front keyboard, with 3 programming keys and display to visualize the parameters and the controller programming.
• All power terminals in 4 mm ø. Signal terminals in 2 mm ø.
• Possibility to connect an external function generator for continuous cycling.
3- ACCESSORIES TO BE SUPPLIED
• Set of connection cables with 4 mm safety connectors. Set of 2 mm cables.
• Function generator used as variable position generator.
Output signals: sinusoidal, triangular, square, 0-10 Vpp. Feed by the Controller Panel.
• Data logger to process the signal coming from the distance sensor. With USB output to PC.
• Set of weights as motor payloads (2 x 1 kg + 1 x 2 kg) with stainless steel container. Therefore, 1-2-3-4 kg loads are available.
• Software: the unit is supplied with a specifi c software (Windows environment), that processes the data sent by the external distance sensor. It allows to calculate and graphically show the mechanical parameters (distance, speed, acceleration, force and power) under different loads.
Power supply: 230 Vac 50/60 Hz single-phase
