Synchronous motors - Import export

Unexcited synchronous motors Reluctance motors are used in textile machinery as drive for godets and spinning pumps. In general they are used in inverter application as single drive or group drive. Reluctance motors can be realised for any voltage/frequency ratio U/f. Speed >15.000min1 is possible. A great no. of variations concerning special shaft, flange bearing and housing is available. Reluctance motors are available for hazardous locations in flameproof design.

Our synchronous and asynchronous machines are distinguished by their high energy efficiency. The motors are reliable, safe to operate and robust. With our three-phase motors we offer special machines for almost any application. They are designed and built for the specific requirements of the respective drive application. We offer individually adapted motors – both in terms of electrical layout and mechanical design. We provide made-to-measure units, for example, for existing foundations or special bearings to absorb additional forces. The power network conditions on site are taken into account for the electrical layout to ensure that only minor voltage drops occur and a reliable run-up is guaranteed. Our portfolio comprises asynchronous motors with cage or slip-ring rotors as well as synchronous motors with brushless or static excitation.

PMmotors with rotorcage for line start The pmexcited reluctance motors are an alternative to the reluctance motors and can be used in identical applications typical for synchronous motors.

GMN high-performance spindles with an integrated motor are designed for those applications and relevant installation situations in close collaboration with our customers. They are available as needed with a synchronous or asynchronous motor, for manual - HGS series - or automatic tool change - HGC, HGT series - and with oil-air or grease lubrication. Additional options are, for example, an AE sensor, vibration sensor or an automatic balancing system.

The B 400 combines great evaporation performance with economical continuous operation in a sturdy housing. Thanks to the permanent rotation, the air is effectively washed and at the same time humidified before being evenly distributed back into the air in the room without condensation, by means of a 2-speed fan. The B 400s quiet-running synchronous motor enables even large rooms to be humidified without running up large electricity bills. B 400 Benefits in practice: Clearly designed operating panel with hygrostat and fan control and level indicators Rotating evaporation fleece cleans and washes the air 2-speed fan Automatic power-off Adjustable vent grid Robust, powder-coated sheet steel construction With built-in brace for optimal air circulation

The rotary table combination RT3A100 consists of two directly driven rotary tables of the RT3A100 series. The B-axis has a swivelling range from approx. -10° to +110°; the C-axis can be rotated infinitely. The unit is driven by two integrated 3-phase synchronous motors. The drive guarantees highest dynamics and precision. An innovative clamping unit integrated in the housing guarantees high holding forces when the drives are switched off without position changes on the axes. By means of compressed are impact, the holding torque can be increased from 15Nm to 20Nm for special applications. The complete system is supplied as ready-to-connect unit.

Rotary tables with direct drive series RT3 The rotary tables with direct drive are available in different types: RT3A100x100, RT3A100x155, RT3A080x130, RT3A150x100, RT3A150x130, RT3A250x170, RT3A200x060 und RT3G630x225 Rotary tables RT3G630 – high dynamics, high precision, high loading capacity This direct driven rotary table RT3G630 has particularly been developed for machine tool industry and assembly machines. It is characterised by its high precision, highdynamics and its high loading capacity. The rotary table is driven by a permanently excited 3-phase synchronous motor. The rotary plate and the housing are made of gray cast iron.

With Conventional Feed Lines, the focus lies on speed and material surface. That’s why Conventional Feed Lines are equipped with a Coil Reel for pull-off, a Straightener with variable frequency drive a coil loop and a Servo Roll Feed: the loop uncouples the more inert straightening process from the highly dynamic indexing process and thus allows for high line speeds and preservation of the material surface. Since productivity and capacity demands can vary significantly, we have created different control concepts: while small Feed Lines work with a simple pneumatic drag brake at the Coil Reel and an ultrasonic sensor to control the Straightener speed, the large Feed Lines get fully synchronized controls with motor-limited Coil Reels and a smart loop, creating a steady average speed of the whole line. This allows smooth pull-off of high coil weights while the loop remains very calm – in addition, the Servo Roll Feed can work with full dynamics, even at long indexing progressions.

nduction Heating and Joining in one turnkey system. This turnkey system is used to heat electric motor housings with various dimensions for a wide range of joining processes. Example Heating System 1: the die-cast aluminium housing for an asynchronous motor (diameter 450 mm) is heated to approx. 290°C in approx. 5 minutes to fit the wound stator package. The parts are loaded and unloaded from the feeding belt parallel to the working time. The heating process takes place in two independent work stations. The generator has a switched output which means that only one generator is required for the two heating stations. The system is controlled using a SIEMENS PLC controller. Example Heating System 2: the aluminium housing (diameter 140 mm) of a synchronous motor is heated to approx. 280°C in approx. 3 minutes to fit the stator. The component is loaded into and unloaded from the heating station semiautomatically. The system is controlled using a PLC.

For this purpose, the current position of the rotor is always measured with a rotary encoder, e.g. an incremental encoder.
