Slip Ring Motor Starter
Magnastart
Magnastart is a unique Inducer system for starting slipring induction motors, offering considerable improvements in maintenance, reliability and cost-effectiveness. Magnastart is used extensively both as a component in new equipment and as a quick and effective replacement for existing resistance and liquid starters. Wide flexibility of tappings allow the impedance to be matched on commissioning. Magnastart has been used with crushers, pumps, fans, conveyers, cranes, mills and presses.
Magnastart Features
- Size: Though physically smaller than conventional systems of resistors and contactors, the large thermal capacity of Magnastart permits the starting of difficult and high inertia loads without problems
- Simplicity: Magnastart requires only one shorting contactor, reducing the system complexity, size and cost
- Performance: Magnastart is ideal for inching, reversing, and plug braking without any additional rotor controls
- Maintenance: Magnastart Inducers have no moving parts, and do not use liquids or chemicals. Magnastart will give many years of service without any maintenance or adjustment
- Reliability: The robust construction permits heavy usage under the most arduous conditions. Built-in thermal cut-out provides protection against damage

Providing both quality and experience the Setzermann division of REO INDUCTIVE COMPONENTS AG produces toroidal current-transformers from with power ratings from 10 VA up to 500 VA. These are available in either standard or custom designs, built to specification and proved in our own test laboratory. The toroidal current-transformers conform to all relevant standards whilst double-isolation and the use of UL approved encapsulation materials are always incorporated in their design. The Setzermann range of current-transformers includes many different styles from those for pcb-mounting to panel-mounting types. We offer our customers a prototyping service before commitment to a final design. Details of all products can be downloaded from our website. Setzermann current-transformers have a good reputation for high-protection and longevity.

Safety transformers of the series TS TSF are particularly indicated to power the temperature monitors and temperature controllers designed for a supply-voltage of 12 Vac.
They get produced in "closed manufacturing", with a plastic box provided of mounting lugs to permit a quick mounting; the electrical connections get done through screw connectors.
TS TSF B and TS TSF D are produced according to EN 60742 norm and defined "safety-transformers", that is why they can fit applications for very low safety voltage on the secondary circuit and for high insulation voltage between the primary circuit and the secondary one.
The protection from short-circuits and overloads is guaranteed for the TS TSF D through an incorporated non self-resetting thermal cut-out, while TS TSF B needs the insertion of a external fusible with the indicated characteristics.

We offer numerous Power Transformers in the toroidal design. For your convenience, we have added the expected DC output, should the transformer be rectified.
The DC output is calculated with a standard full-wave bridge rectifier with a large capacitor. Any of these primaries can be easily used to configure custom secondaries at a reduced cost compared to a full custom design.
