This paper will evaluate the underlying technology of magnetic encoders and illustrate the benefits and design tradeoffs to consider in a surgical hand tool or surgical robotic application.

Reducing Surgical Hand Tool Size Without Sacrificing Performance

This paper explains how to minimize the size of the motor required for an application while balancing tradeoffs in other design parameters.

Every Drop Counts: Designing Motors to Optimize Home and Ambulatory Infusion Pumps

The challenge for a home and ambulatory infusion pump designer is to create pumps that provide mobility and patient comfort while not sacrificing any quality of care.

Thermal Considerations for Ironless Brush DC and Brushless DC Motors

One of the biggest challenges for electric motor manufacturers is to ensure that the instant internal temperature of the motor never exceeds its various components’ maximum, admissible temperature.

Customized and Reliable Stepper Motors for Damper Applications

When designing an external mount electrical damper actuator, there are major miniature motor design elements that should be considered.

Slotless vs Slotted Brushless DC Motor Designs

Electronically commutated miniature motors continue to gain interest due to their simple construction and long operational life time.

Controlling Brushed DC Motors Using PWM - Optimal Frequency, Current Ripple, and Life Considerations

With a proper design of PWM, the eddy current effects can be minimized, allowing the motors to be optimally driven.

Thermal Sensor Management

Portescap provides a Resistance Temperature Detector (also known as RTD), specifically a Negative Temperature Coefficient (NTC) for which the resistance decreases when the temperature increases.

Determination of Rotor Temperature Under Steady State Conditions

This technical note derives a straight forward method to determine the rotor temperature for constant torque applications and variable duty cycle/torque applications where the duty cycle is less than or equal to one fifth the thermal time constant of the rotor.

High Speed Linear Actuators

In this article, we are looking for motors for possible high speed linear actuation. Due to its precise positioning capability, only stepper motor is examined here.

Eliminate Design Compromises in Industrial Power Tools

Industrial power tools (IPT) have an operating profile quite different from other motor-driven applications. A typical application requires torque output from the motor throughout the motion.

Motion Solution for Electric Expansion Valves

When set and controlled properly, an expansion valve will keep the evaporator active throughout its operation.
