Electrical Characteristics

Rated Power
The power ratings given in the lists are the power outputs according to VDE0530 for continuous operation S1; frequency 50 Hz; max. room temperature 40°C; max. site altitude 1000 m above sea level.

Rated Voltage and Frequency
The standard voltage ratings are 230/400 V or 400/690 V and rated frequency 50 Hz. Voltage fluctuations within +/-10% are permitted. Special voltages and special frequencies are available for export, inverter operation and use in battery-powered machines.
Two-speed motors, especially those with Dahlander circuits, are designed for one voltage only. They are supplied for power supply 230 V or 400 V at 50 Hz. Other voltages or frequencies are possible. Motors with two separate windings can be designed for two voltages in the ratio of 1:1.73. Further details upon request.
Outputs for single-phase motors are based on a rated voltage of 230 V, 50 Hz..

Rated Currents and Efficiencies
Currents and efficiencies given in Table 1 are based on a rated voltage of 400 V / 50 Hz and full-load rating. If the rated voltage changes the rated current is converted as follows:
J’ = 400 x J / U’

Starting Current and Starting Torque
Starting torques and currents are a multiple of the rated values with direct starting.

Overload Capacity
In accordance with VDE0530 the motors can withstand 2 minutes at 1.5 times rated current at rated-load operating temperature without damage to the winding.

Motor Torque
The motor torque output at the shaft in Nm is:
T [Nm] = 9550 x P [kW] / n [min-1]

Temperature Class
ABM electric motors are manufactured using high-grade "Overcoat" enamelled wire and wrapper material in conjunction with solvent-free resin impregnation and meet temperature class F. Maximum temperature is 155°C. A line-side circuit-breaker with overtemperature switch provides the motor with reliable protection in the event of an overload. For severe operating conditions (e.g. converter mode, very high inertia starting and switching operations with more than 100 c/h) we recommend the use of temperature sensors PTC thermistors (see Options).
