EEM41 Three-phase asynchronous machines Safety
Basic safety instructions
In all experiments using mains voltages high, life-threatening voltages arise. For that reason use only safety measurement leads and make sure that there are no short-circuits.
It is imperative that all of the devices, which are provided with an earth or where earthing is possible, must be earthed. This is particularly the case for the frequency converter being used.
Always be very careful to check the wiring of the application modules and only switch on the mains voltage after a check has been completed. Whenever possible use a robust current monitoring instrument in the circuit.
Always use shaft-end guards and coupling guards as protection against contact with rotating motor parts
All locally applicable stipulations and standards governing how electrical equipment is handled must be complied with.

General instructions on handling the equipment
{ Check that the knurled screws at the base of the motor and the coupling sleeves (power grip) on the motor shaft are all securely fastened.
{ Use shaft and coupling guards. { Any prolonged running of the machines when operating under high loads
can subject the machines to excessive heating. { The extreme case of the machine being prevented from rotating entirely
may only arise briefly. { All of the machines are equipped with a thermal circuit-breaker, which
triggers when the maximum permissible operating temperature is exceeded. These switching contacts are accessible on the terminal board and must always be connected to the corresponding connection sockets of the mains supply and control unit.
{ All measurements have been recorded using conventional measuring instruments (primarily class 1.5) at the standard mains voltage (230/400V +5% -10% 50Hz) using standard production machines. Experience suggests that measurements will lie within the tolerance range of +/-15% with respect to the specified measurement. For more information on this please refer to VDE0530.

EEM41 Three-phase asynchronous machines Asynchronous motor
Definition of rotation direction If you look at the drive shaft end of the asynchronous machine from the perspective of the working machine (in our case the brake), the rotating direction is positive when it is clockwise. If the motor has two workable shaft ends, then it is the shaft end opposite the cooling vents, collector or slip-rings that is the shaft end which defines the rotation direction.
Note: in the "Classic series" (0.3 KW & 1.0 KW) the rotation direction is determined by the rotation direction of the brake, i.e. if the asynchronous machine rotates clockwise, i.e. in the positive direction, the control unit of the brake indicates a negative rotation direction. Thus the rotation direction displayed is always that of the brake.

z Identify the difference between clockwise and anti-clockwise rotation
