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

Schurter ADO Automotive Fuses for High Voltages

  • Automotive fuses 10x38
  • High breaking capacity up to 50 kA
  • 4 mounting options (3 x Bolt-on, 1 x PCB)
  • Wide range of applications in the DC area

The new Schurter ADO series is a fuse with a rated current range of 10 to 63 A and a maximum operating current of 40 A at 1000 VDC. It is designed for applications in direct current systems up to 1000 VDC and is particularly suitable for use in electric vehicles.

The fuse has a fast tripping characteristic, high current carrying capacity and good vibration resistance. The ADO series is UL-certified for 500 VDC. Technological features such as a patented filler formulation and special curing processes ensure safe arc extinguishing and prevent secondary arcing.

Mounting Options
A total of 4 mounting options are provided in the Schurter ADO fuse family. In addition to a conventional variant for PCB assembly, there are 3 for screw mounting. The screw variants ensure a firm, mechanical fit even in the event of strong vibrations. They are also ideal for applications where high currents flow, as the contact resistance is low. The screw variant also offers advantages in terms of maintenance (can be replaced after tripping).

Description

  • High breaking capacity of 20 kA @ 1000 VDC
  • Bolt-on mounting and PCB / THT mounting for vehicle applications

ADO Fuse Characteristics

  • High temperature resistance
  • Mechanical vibration and shock resistance
  • Chemical load resistance

Applications
The new ADO fuse family has been specially developed for applications in the automotive sector.

  • Battery Management System
  • On-Board Battery Charger
  • DC/DC Converters
  • Air-Conditioning Compressor
  • PTC Heater
  • PDU: Motor Control Unit / Controller

Technical Data

  • Rated Voltage 500/750/850/1000 VDC
  • Rated current 10 - 63 A
  • Breaking Capacity up to 50 kA
  • Characteristic EV Fuse
  • Mounting PCB/THT, Bolt-on
  • Admissible Ambient Temp. -40 °C to 125 °C
  • Material: Terminals Copper alloy, tin or nickel plated
  • Material: Tube Ceramics
  • Material: Endcaps Copper Alloy
  • Storage Conditions -40 °C to 70 °C, max. 70% r.h.

Schurter MSS-IO: Electronic Switch with IO-Link Interface

Image

With the MSS-IO, Schurter is entering the field of bidirectional communication via switches in industrial automation. The MSS-IO is based on the successful Schurter MSS electronic switch, which has been expanded to include an IO-Link module.

Schurter mss10

The MSS-IO switch from Schurter is based on wear-free resistance measurement and completely avoids mechanical components. Instead of capacitive technology, a precise change in electrical resistance is used for switch detection: sensitive enough to detect the smallest changes in pressure, robust enough for industrial series processes. Ultrarugged, precise and easy to integrate.

IO-Link Interface
The IO-Link interface allows bidirectional communication, parameterization during operation and real-time diagnostics. The connection is made via standard M12 connectors. Predictive maintenance and simple integration into existing Industry 4.0 environments are guaranteed.

Features

  • IO-Link Communication protocol
  • Resistive electronic switch (LA) / pushbutton (MO) without moving parts
  • Triggering of the switching mechanism by light pressure on the switching surface
  • Multicolor illumination
  • Hygienic operation
  • Trendy design
  • Insensitive to water
  • Side illumination
  • Wearless - no moving parts

Easy to Clean
Thanks to the closed surface, the switch is insensitive to water, dirt and cleaning substances. This is a clear advantage in hygienically sensitive areas such as food processing or laboratory automation. The absence of moving parts minimizes the maintenance effort and increases the service life enormously.

Applications

  • Automation Technology
  • Robotics
  • Hygiene-Critical Applications
  • Scenarios with High Demands on Precision, Process Reliability & Digital Communication
