High speed brushless motors. (Advertisement).Maxon's new "EC" series of brushless motors are electronically commutated enabling extremely long motor life. This also minimizes electrical noise. Hall effect sensors A Hall effect sensor is a transducer that varies its output voltage in response to changes in magnetic field. Hall sensors are used for proximity switching, positioning, speed detection, and current sensing applications. are built in to the motor in order to provide feedback to the control electronics. By assembling the coils outside the motor, good heat dissapation and high overload See information overload and overloading. capability is attained. Continuous output power is 20 watts and maximum speed is 50,000 RPM. Ambient temperature Outside temperature at any given altitude, preferably expressed in degrees centigrade. range is -20[degrees] to 100[degrees] C (-4[degrees] to 212[degrees] F). Utilizing high-energy neodymium neodymium (nē'ōdĭm`ēəm), metallic chemical element; symbol Nd; at. no. 60; at. wt. 144.24; m.p. about 1,021°C;; b.p. about 3,068°C;; sp. gr. 7.004 at 20°C;; valence +3. Neodymium is a lustrous silver-yellow metal. magnets results in a very responsive mechanical time constant of 6.5 ins, while minimizing overall size. Complementing the motors are gearheads with ratios from 4.4:1 to 4592:1 capable of 0.45 Nm (63 oz-in) of intermittent torque. Contact Mr. James Talent. Maxon Precision Motors, Inc., Burlingame, CA.
