Greiffenberger0214With his "Sinochron "engines ABM Greiffenberger meets the increased requirements for effective logistics solutions. The highly dynamic motors are particularly energy-efficient and have good control properties. They have their strengths especially in the partial load range, because among other things it has hardly any rotor losses.

In intralogistics, especially in conveyor technology, more than two thirds of the drives are operated in the partial load range. This means that the torque provided by the engine is only fully requested for a short time to start the load. Afterwards, the drives usually run with only 20 to 30% of the rated load. This is exactly where the Sinochron drive scores. Decisive for this is a permanently excited synchronous motor, which has almost no rotor losses.

In contrast to the widely used asynchronous machine, synchronous motors are generally characterized by high efficiencies, high power density and compact dimensions. Conventional synchronous drives require a speed sensor for operation on the servo drive or frequency converter. Due to the special features of the presented Sinochron development, the motors are very well suited for sensorless controlled operation and thus offer an economical alternative to expensive servo drives. At the same time they stand out due to a higher dynamics and better efficiency of asynchronous motors.

The very good efficiency especially in the partial load range, the engines owe also the use of high-quality magnets of neodymium-iron-boron, which prevent the rotor losses. A higher power density and the associated smaller volume compared to an asynchronous motor are further features. Especially in conveyor technology, drive solutions often have to be installed in confined spaces.

The structurally simple and thus robust design as well as the omission of the mechanical speed sensor including cabling make the Sinochron motor particularly reliable under very harsh environmental conditions such as in the deep-freeze warehouse. The drive with good concentricity is designed for use over the entire temperature range up to -30 ° C. From the asynchronous motor, it differs by about twice as high short-term overload capacity. Applications can be found in conveyor drives, textile and packaging machines, industrial doors, screw compressors or in medical technology.
