Motor Type & Specifications

	Linear Motor Type:
	Your choices are...
	Moving Coil		Coil moves and the magnet is fixed, such as an audio speaker.
	Moving Magnet		Magnet moves and the coil is fixed.
	AC Switched Reluctance Design		Types of AC synchronous motors.
	AC Synchronous Design		Class of motors that operate at constant speed up to full load. The rotor speed is equal to the speed of the rotating magnetic field of the stator; there is no slip.  Reluctance and permanent magnet are the two major types of synchronous motors.  A synchronous motor is often used where the exact speed of a motor must be maintained.
	AC Induction or Traction Design		Class of motors that derives its name from the fact that current is induced into the rotor windings without any physical connection with the stator windings (which are directly connected to an AC power supply); adaptable to many different environments and capable of providing considerable power as well as variable speed control.  Typically there is "slip," or loss of exact speed tracking with induction motors. Typically rolled flat version of rotary AC induction motors.
	Linear Stepping Design		A stepper motor uses a magnetic field to move a rotor in small angular steps or fractions of steps. Stepper motors provide precise positioning and ease of use, especially in low acceleration or static load applications.
	DC Brushed Design		Brush motors have the armature windings on the rotor.  The magnetic fields are commutated via direct contact of brushes with the rotor commutator.
	DC Brushless Design		Brushless motors have their armature windings on the stator and the field on the rotor.  They rely on internal noncontact sensing devices to activate external commutating electronics.

Features

	Forced Air Cooling?		Active fan or other air-moving device.

Environment

	Operating Temperature:		The temperature range over which the device must operate.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
	Maximum Shock:		The maximum shock you require the device to survive. Items that are 'typical' may not explicitly give their Max Shock value, so it is a good idea to use this only when working with extremes.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Maximum Vibration:		The maximum vibration you require the device to survive. Items that are 'typical' may not explicitly give their Max Vibration value, so it is a good idea to use this only when working with extremes.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
