Motors

What are the different types of Motors?

AC Motors (Alternating Current)

Synchronous Motors:

  • Excited Synchronous Motor: Requires a separate DC supply for the rotor.
  • Reluctance Motor: Uses magnetic reluctance to generate torque.
  • Hysteresis Motor: Utilizes hysteresis in the rotor material for smooth operation.

Asynchronous (Induction) Motors:

  • Squirrel Cage Induction Motor: Commonly used due to its simplicity and durability
  • Slip Ring (Wound Rotor) Induction Motor: Allows for control of the rotor resistance

DC Motors (Direct Current)

Brushed DC Motors:

  • Series Wound DC Motor: High starting torque, used in traction applications.
  • Shunt Wound DC Motor: Constant speed, used in applications requiring stable speed.
  • Compound Wound DC Motor: Combines series and shunt characteristics.

Brushless DC Motors:

  • Permanent Magnet DC Motor (PMDC): Uses permanent magnets for the rotor.
  • Coreless or Ironless DC Motors: Lightweight and efficient 

EC Motors (Electronically Commutated)

  • Energy Efficiency: EC motors consume less power compared to traditional AC motors, making them ideal for HVAC systems and industrial applications.
  • Brushless Design: Unlike conventional DC motors, EC motors use electronic commutation instead of carbon brushes, reducing wear and maintenance.
  • Integrated Electronics: They have built-in controllers that optimize performance and allow for variable speed control.
  • Compact & Versatile: EC motors are commonly used in fans, pumps, refrigeration systems, and ventilation units

Why Choose E. Preston?

Since our inception in 1980, our business focus has been on providing two things: a reputation for outstanding customer service, and an unbeatable range and stock of electrical and electronic components.

We feel we have achieved that at E Preston, and that probably explains our company growth over the years. We do not want to become complacent though, and we always work hard to exceed customers’ expectations when they deal with us, if we can.

Our service is unashamedly a little old fashioned, ensuring we follow up on promises to customers, and phoning back when we said we were going to. We also do our best to ensure the customer receives their order next day. You can also talk to us about flexible payment terms, if needed.

Please contact us if you need technical assistance about them or any of our products – our team of expert operatives will be happy to help.

to discuss your needs.

Wieland gesis® NV Signal Connector

Image

The connector system for quick, easy, and safe bus cabling and signal applications. It meets all the requirements of modern building installation.

Wieland NV Pic

Low-Voltage Technology
These connectors are used to distribute signals in buildings, in parallel to the distribution of power. Mechanical coding and clear assignment with different colors facilitate assembly. Complex installations can be realized with just four basic components – from the sub-distribution unit to any point of use. The connectors come as male and female connectors complete with strain relief and can be used to connect any current type of cable.

The BST14 are designed according to the KNX manual.

The 5G2.5/4+2X1.5 flat cable with shielded bus, as per the KNX manual, is available for the combined distribution of energy and signals.

Best Choice Value Program
This product is part of our exclusive Best Choice program and has been carefully selected to provide you with maximum efficiency, reliability, and flexibility.

  • Proven quality: Meets the highest standards and is ideal for plug-in electrical installations.
  • Quick availability: As a Best Choice product, it benefits from prioritized stock and is always ready for short-term delivery.
  • Perfect for your application: Ideal for common applications and seamlessly compatible with our system solutions.

Schurter APO: Pyrofuse

Schurter APO1

APO: Active Safety for High Voltage Systems

  • Quick Response
  • Triggered actively
  • Low temperature rise
  • Reliable Operation

Electrification is advancing across all industries – from electric vehicles and charging infrastructure to energy storage, aerospace, and fuel cells. As a result, the demand for reliable protection mechanisms in high-voltage systems is increasing. With the new Pyrofuse-APO Series, Schurter launches a fuse technology that sets a new benchmark for safety.

Unlike conventional fuses, the APO Fuse operates actively. In the event of a short circuit or accident, the control unit sends a trigger signal to an integrated micro gas generator. Within milliseconds, the generator produces high pressure that drives a piston to mechanically sever the solid copper busbar. The resulting arc is safely suppressed in a dedicated extinguishing chamber. The outcome is a complete galvanic isolation in less than two milliseconds – with measured values as fast as 0.9 ms.

The APO Series is rated for operating voltages up to 1000 volts and continuous currents up to 400 amperes. With an ultra-low internal resistance in the range of only a few dozen micro-ohms, power losses and temperature rise remain minimal. Its high breaking capacity ensures safe interruption even under extreme short-circuit conditions, while the fully encapsulated design prevents the release of gases or particles.

This unique combination of speed, robustness, and efficiency guarantees maximum system safety. At the same time, the compact design allows for seamless integration into existing architectures and relieves downstream components such as contactors.

With the Pyrofuse-APO Series, Schurter strengthens its position as a technology partner for emobility and the energy transition. Whether in electric vehicles, aerospace applications, or stationary storage systems, the APO Fuse ensures that high-voltage systems remain reliably protected – even under the most demanding conditions.
