1.1 Overview This training workbench include various motor application circuit, through experiment, students will be familiar with motor features, mater control principle and control method. It stress on hand on operation ability, and training practice. It’s suitable for college, technical schools, university,training institute. 1.2 Character (1) Training workbench use aluminum column structure frame, it include meter box and power box to test and measure technical parameter, it is easy to use and it is not easy to be broken. (2) Equipped with motors, students can make combination, and finish many training contents. (3)Training workbench has high safety system. 2 Technical parameter (1) Input power: three, five wires,380V±10% 50Hz (2) Dimension: 1600mm×800mm×1750mm (3) Whole capacity:＜2.0KVA (4) Weight: ＜300kg (5) Work condition: Environment temperature:-10℃～+40℃ Relative humidity: ＜85%(25℃) 3 Product consist of 3.1 Power control panel Power control panel use aluminum structure metal panel, all close type boxes structure 3.2 Training workbench Training workbench use aluminum structure. There are universal 4 wheels at the bottom of workbench, there are 2 breakers on wheel. The trainer can be moved or stop convenient . The workbench panel thick is 25mm high density substrate , there is high temperature high pressure anti-fire treatment process. It equip with three guide rail type drawer, 2 push and plug cabinet. The structure is sound and reliable, outlook is beautiful. 3.3 Power control panel (1) Single phase, three wire power input, it has been tested by leakage breaker control, it has emergency stop button, you can cut off electricity when emergency. (2) Control panel has two point type voltage meter, one current meter, one power meter, one non power meter. (3) It equipped with indicator, Europe power plug output, safety output sockets. (4) DC 0-220V continuous adjustable DC armature power, AC220V,AC380V, with short circuit protection function. 3.4 Equipment composition (1)Transformer module This training bench consist of two groups of transformer training module, they are single phase transformer and three phases transformer. The input of single phase transformer is AC 220V or AC 380V, output is AC 110V, AC 36V, AC 24V and AC 6.3V. Three phases transformer input is three phases AC 380V, (2) Resistance load module This training bench contains a resistance load module, consist of two groups of fixed value resistor (3) Three phase self-coupling pvoltage adjustment module This training bench equipped with a three phases self coupling voltage adjust module, its power input and power output connect through 4mm safety termnal, three phases self cupling voltage adjust module is shown in below photo, among them, power input terminal is A ,B,C, powre output termnal is a,b,c. (4) Hanging box module This training workbench consist of 9 hanging module, it is shown in below photo: they are resistance load module, capacitive load module, bulb load module, button load module, one AC relay module, one time relay module, three AC contactor hanging module. Students can connect through 4mm safety electrical cable do related experiments. (5) Motor module This training bench consist of 6 types of motor, they are fixed on the experiment plate separately. Among them, the motors can be connected by coupler, to do the experiments. When motor connecting, lossen the bolt at the bottom of motor base, so can slide the motor, and connect with nearby motor,
