Description

The principle of the bench is to study and characterize the behavior of 4 different types of electric motors (asynchronous, synchronous, brushless and direct current), to study their control modes and associated protections

The wiring of the control and power part is carried out using 4mm double well safety cables, with a keying to prevent crossings between 24V control circuits and 230 or 400V voltages.

It is equipped with a charging motor that allows a resisting torque or a driving torque to be applied to the motor to be studied by means of a mid-point potentiometer.

The bench is fully instrumented for the measurement of engine torque, speed, active power of the wiring and is supplied with a quality clamp meter allowing precise readings to be taken at different points :

• Measurement of DC and AC voltages up to max. 600 V
• Measurement of DC and AC currents up to max. 100 A
• Measurement of resistances up to 20 MΩ
• Continuity check (< 10 Ω, acoustic), Diode test, Capacitance measurement up to 2 mF, Non-contact voltage detector (NCV function) ≥100 - 600 V/AC and at a distance ≤15 mm

The whole thing is completely safe and prevents any operation if all the components and protective elements are not in place.

The rugged design of this equipment makes it perfectly suited for use in a school setting.

Its anodized aluminum structure on wheels gives it a very high robustness as well as great flexibility of integration into your premises.

The manufacture of this equipment complies with the European Machinery Directive
