Low Voltage Motors
Motors that do not exceed a voltage of 1000 V and deliver a maximum power of 700 kW.
Other versions can be combined with the low-voltage motor (e.g. brake motors). The motors are designed for use in potentially explosive areas. Note: Special motor versions can be selected directly via the corresponding category.
High Voltage Motors
Motors that have a voltage between 3 and 6.6 kV and can deliver an output of 160 to 710 kW.
The combination options with attachments and superstructures are very limited compared to low-voltage motors.
The high-voltage three-phase motors are explosion-proof in the “flameproof enclosure” ignition protection type according to DIN EN 60079-1 for groups IIC and temperature classes T3 to T6. The thermal utilization corresponds to thermal class B. The limit to class F is only slightly exceeded in special cases.
Axial Ventilated low Voltage Motor
Very quiet version – noise class 3 (type …A)
For particularly high demands on a low-noise version, we have developed a very quiet surface-cooled three-phase motor. These motors are around 12 dB(A) quieter than the standard version with radial fan in the 2-pole version and achieve a further reduction in noise compared to the low-noise version with axial fan.
This system is fully suitable for converter operation.
For higher demands, the low-noise version with a direction-dependent axial fan is recommended (type …AR). These fans are available for 2-pole motors from size 112 and for 4-pole motors from size 132. The aerodynamic design of the fan blades and the optimal angle of attack mean that the noise of the 2-pole motors can be reduced by up to 10 dB(A) compared to the standard version. This system is fully suitable for converter operation.
Water-Cooled Low-Voltage
The water-cooled motors offer the following advantages:
This system is fully suitable for converter operation.
Externally Driven Axial Fan
With forced ventilation, the motor is cooled by a separate forced cooling fan motor with axial ventilation. The external fan motor allows for independent cooling.Motor With Built-In Brake
The brake is installed in a pressure-tight housing and combined with the motor on the non-drive side to form a single unit. This is possible for sizes 80 to 132. The system is maintenance-free until the brake pads wear out.
Build-On Brakes
The brakes are used to limit and regulate the rotation speed of the motor or can also be used as a holding brake for positioning e.g. conveyor belts.
Motor With Encoder Attachment
Incremental encoders are used for electrical position determination and motor speed control. These devices convert the input variable “speed” into an analog or digital electrical signal. Attached devices are connected in a separate terminal box.
Motors Without Ventilation
The motor has no ventilation. Cooling occurs exclusively via the surface.
