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 DMTH Pic

DMTH: The Industry Standard 2.54mm THT-DIP-Switch

  • 2.54mm standard pitch design
  • Low profile
  • High number of cycles
  • Through hole terminal

The DMTH series is a robust and cost-effective DIP switch designed for reliable manual configuration in industrial and electronic applications. Featuring the industry-standard 2.54mm pitch and THT mounting technology, it offers excellent compatibility with established PCB designs while ensuring secure mechanical retention and soldering reliability.

With up to 12 positions, SPST contacts, recessed or raised actuator options, and a low-profile 3.6mm design, DMTH supports flexible system configuration without increasing board space requirements. The switch is rated for up to 2,000 operating cycles and operates reliably from -40°C to +85°C.

Typical applications include address setting, communication protocol selection (e.g. RS-485, Modbus), function control, BIOS and hardware configuration, medical equipment parameter settings, HVAC systems, industrial controllers, robotics and consumer appliances. Combining proven performance, competitive cost and fast availability, DMTH is an ideal solution for OEMs seeking a reliable alternative to premium-priced DIP switch brands.
