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

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.
Honeywell NGC Series MICRO SWITCH Compact Limit Switches
Honeywell MICRO SWITCH Compact Limit Switches, NGC Series, are a configurable platform of medium duty switches that allow the customer to choose SPDT (single pole, double throw) or DPDT (double pole, double throw) circuitry while maintaining the same housing and mounting footprint throughout the NGC Series.
MICRO SWITCH NGC Series can be configured more than 380,000 ways, carries global approvals, and are sealed to IP67 for potential use in indoor and outdoor applications.
With two times the vibration (10 g) and shock (50 g) ratings of comparable competitive devices, the NGC Series can be implemented in the harshest of environmental conditions, providing enhanced reliability and repeatability.
Broader current capacity (10 A) than comparable devices allows for potential use in a wider set of applications, making platform standardization an easier task.
Features: • SPDT or DPDT configurable circuitry • Snap-action, positive-break contacts • Silver alloy and gold-plated contact options • UL, CE, UKCA, cUL, and CCC approvals • Conforms to IEC 60947-5-1, IEC 61373, EN 45545-2 • NEMA 1, 4, 12, 13; IP67 sealing • Metal and plastic housing options • Low and high temperature variants • Cable and connector terminations • Variety of heads and actuator levers
Applications: • Boom position detection • Elevators and escalators • Machine tools • Mobile light towers • Packaging equipment • Rail doors • Scissor lifts
Value To Customers
Cost-Effective: Provides a single source for a compact SPDT and DPDT limit switch, which can help minimize the Original Equipment Manufacturer’s sourcing expenses by simplifying their supply chain
Versatile: Durable packaging allows for use in many harsh indoor or outdoor applications, providing performance confidence
Configurable: Allows design engineers to standardize on a single footprint while meeting a variety of electrical requirements
Application Support: Customers with a global footprint can count on Honeywell for regional support for new applications and troubleshooting
