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.
Honeywell RTY Dual-Output Hall-Effect Rotary Position Sensor
RTY Dual Output Sensors - Designed to provide non-contact sensing in harsh transportation and industrial applications
The Honeywell RTY Dual Output Hall-effect Rotary Position Sensors are designed to provide non-contact sensing in harsh transportation and industrial applications with safety redundancy.
The rise of smarter controls in transportation and industrial equipment has been enabled by accurate, reliable, and rugged sensing technology. Hall-effect style sensors provide a portable, non-contact solution that can handle tough operating conditions in these environments.
The RTY Dual Output Series joins the extensive Honeywell portfolio of rugged and reliable Hall-effect Rotary Position Sensors. The addition of the RTY Dual Output Series brings the durability and reliability of our Rotary Position Sensors into customer applications requiring safety redundancy.
About RTY Dual Output Sensors: The RTY Series Hall-effect Rotary Position Sensors provide non-contact sensing in harsh transportation and industrial applications at a competitive cost.
These shaft activated products are available in two versions: an integral shaft with or without a lever. The lever may allow customers to reduce the number of mechanical linkages required for their applications, which may reduce the cost of the overall customer solution.
These products use a magnetically biased, Hall-effect integrated circuit (IC) to sense rotary movement of the actuator over a set operating range. Rotation of the actuator changes the magnet’s position relative to the IC. The resulting flux density change is converted to a linear output.
Key Features:
True non-c ontact operation:Ensures long-lasting performance with a product life of 35 million cycles•Solid-s tate Hall-e ffect technology:Provides accurate and reliable sensing
Dual signal capability:Delivers two voltage output signals for enhanced functionality
Rugged design: IP67 and IP69K-sealed package with integral connector for durability in harshenvironments30 September 2025
Automotive-g rade testing:Includes EMI/EMC testing, integrated reverse polarity, and short circuit protection
Applications:
Transportation: Ideal for position and movement detection in trucks, buses, off-road vehicles, cranes, and more
Industrial: Suitable for valve control, HVAC damper control, and irrigation equipment pivot control
Marine:Perfect for tilt/trim position and rudder position monitoring
Military:Effective for chassis suspension systems position height
