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

UHS Fuse 50-100A, 32/50VDC, 8.4 x 9.4mm

Schurter UHS Fuse

The Schurter UHS is a compact, fast-acting SMT/PCB fuse designed for Separated Extra Low Voltage (SELV) applications where high breaking capacity and fast tripping are required.

Description:
This fuse was specially developed for SELV applications with
high rated currents for highest breaking capacity demands.
Thanks to its design, the fuses tripping time minimizes excessive
temperature dissipation at 2x rated current.

Features:

  • High breaking capacity up to 2000A
  • Safe tripping in 10s at twice the rated current
  • High range of operating temperature
  • Small component height of 4.7mm

Applications:

  • Automotive
  • Telecom equipment
  • Datacenter appliances
  • Power tools
