Koford's high performance 36 mm slotless brushless motors feature an internal control which will turn off the motor if the temperature exceeds the maximum winding temperature.

Koford Engineering LLC (Winchester, OH) has introduced a new line of high performance 36 mm slotless brushless motors that offer over-temperature protection. Specifications include:

• Thermistor temperature sensors that are embedded in the windings are available on both sensorless and hall sensor motors to provide a temperature signal to a system controller for over-temperature shut down and fault indication.
• An internal control which will turn off the motor if the temperature exceeds the maximum winding temperature.
• Available in 2 and 4 pole designs and with hall sensors or sensorless with power outputs 10 to 620 watts.
• Available speeds from 3,600 up to 30,000 rpm, and efficiencies up to 90 percent.
• Mechanical time constants are as low as 4ms. 
• A slotless design eliminates cog and allows for precise servo motion compared to conventional toothed motors.
