Description of the RACO – Motor
RACO offers three-phase motors, in 2- or 4-pole design with a power from 0,1kW up to 0,7kW. Every
RACO motor is equipped with thermal contact (optional with thermistor) and can be used limited in
combination with a frequency inverter.
Motor sizes and design
RACO provide its motors with following performance datas in one motor size according RACO works
standard specification.
Performance characteristics
RACO motor
Power supply:
3 x 400V/AC...460V/AC 50 Hz / 60 Hz
Special voltages of 3x42V/AC up to 3x690V/AC are possible
Rated power:
0,10 kW – 0,70 kW
Rated voltage range A:
50 Hz, 2-4 pole (3000/1500 1/min)
Protection class:
IP 54 (IP 65 optional) according DIN EN 60034-5
ISO class (heat class):
F
Ambient temperature:
-20°C to +40°C max. +70 °C in S3 cycle mode
Insulation class (heat class)
The insulation systems of machinery must be allocated to a heat class according to IEC 85. The mo-
tors will be offered in insulation class F.
In the tropical protection version, the copper winding is impregnated with a special coating.
Converter operation
In converter operation, it should be noted that as a result of the upper wave content of the voltage, the
frequency converter leads to increased losses in the motor.
Depending on the speed setting range, counter-torque progression, load play and converter type, the
possible performance reduction and choice of cooling method must be taken into account. RACO mo-
tors should basically be operated as a maximum from 500 V power supply systems, taking into ac-
count the voltage load on the insulation system by the converter.
The operating method of the motors in converter operation must be adapted to the non-ventilated de-
sign, i.e. higher load torques at low speeds can in the case of long running times lead to impermissible
heating and actuation of the thermo-switch. The use of an optionally available thermistor is recom-
mended. The corresponding type of operation should be taken into account in the form of higher de-
signed performance or a ventilated version.
Notice!
The RACO Electric Actuator may be mounted and connected only when
the information regarding voltage and frequency on the type plate
matches the mains supply and the RACO Electric Actuator is intact.
DANGER!
Electrical installation only by qualified staff!
Installation and assembling of electrical equipment has to be done by a
qualified electrician according to local regulations. The connection has
to be done according to the wiring diagram and the type plate.
