  Microstepper Motors

  . Such large step size can also cause motor-shaft oscillations at resonance points that occur at low speeds. But there is a widely used technique that retains the advantages of step motors and overcomes low speed roughness and low resolution. The technique is called microstepping (micro stepping). Microstepping increases the position resolution and smoothness of conventional hybrid step motors. This is done with electronic control in the drive circuits. The drive subdivides each full step...

  Induction Motors

  by inserting different values of resistance in the rotor circuit. Wound rotor motors are generally started with secondary resistance in the rotor circuit. This resistance is sequentially reduced to permit the motor to come up to speed. Thus the motor can develop substantial torque while limiting locked rotor current. The secondary resistance can be designed for continuous service to dissipate heat produced by continuous operation at reduced speed, frequent acceleration, or acceleration with a large...

  reduced to permit the motor to come up to speed. Thus, ac motors can develop substantial torque while limiting locked-rotor current. This secondary ac motor resistance can be designed for continuous service to dissipate heat produced by continuous operation at reduced speed, frequent acceleration, or acceleration with a large inertia load. External resistance gives ac motors a characteristic that results in a large drop in rpm for a fairly small change in load. Reduced ac motor speed is provided... (read more)

  Custom Stepper Motors

  in an overlap mode, these stepper motors can move at half step angles and double pulse rates. These stepper motors produce a net output velocity, which remains the same. Stepper Motor - Permanent magnet. PM stepper motors generally are thought of as low-torque, large step-angle devices. Torque developed by the stepper motors is far below that for equivalent-size hybrid stepper motors, and step angle generally is 90 or 45. Position resolution, moreover, is on the order of +10% of step angle, a value... (read more)

  Sensorless Motor Drive for Harsh Environment

  with recovery. One of the most common failure modes for brushless motors when operating in a harsh down-hole environment is not the motor itself, but the feedback device. Halls are the most common choice for oil services tool applications because of size, but there are trade-offs in performance and reliability. A resolver can provide increased reliability, but they are often as large as the motor and add complexity to the drive electronics. Down-hole services companies have been in search of a Sensorless...

  Disc Motors

  and acceleration much faster than conventional motors. Most disc motors are rated for peak currents of 10 times the continuous rating to overcome load inertias during acceleration and deceleration. Conventional motors are usually limited to peak currents of only two to three times continuous rating. Otherwise, higher currents produce a large magnetic field in the armature that can demagnetize the magnets. Another type of flat servomotor for microstep positioning has a slightly different...

  AC Linear Motors

  The first linear motor was conceived by Wheatstone more than 100 years ago. But large air gaps and low efficiencies prevented linear motors from being widely used. Though motors still have relatively large air gaps, linear induction motors are increasingly chosen for material-handling applications because they are quieter, more reliable, and less expensive than rotary electric motors. And because linear motors do not drive gearboxes or rotary-to-linear conversion devices, they can be more... (read more)

DC Servo Motor Selection. The first selection approach is to choose a DC servo motor large enough for a machine that has already been designed; the second is to select the best available servo motor with a specific feature and then build the system around it; and the third is to study servo motor performance...

  Limited-Angle Torque Motors

  reluctance path and relatively large air gap. Toroidally wound armatures, moreover, are typically molded onto the stator, which protects the windings from damage and holds them in place. Uniform reluctance paths also make toroidally wound LATs suitable for use as limited-angle tachometers. Here, the motors are often used in pairs, one as a torquer and the second as a tachometer. The tachometer provides a reference speed signal for the motor-control circuit. LATs produce torque through a rotation... (read more)

  Custom DC Motors

  consideration of several factors. DC Motors - Speed range. If field control is to be used, and a large speed range is required, the base speed must be proportionately lower and the motor size must be larger. If speed range is much over 3:1, armature voltage control should be considered for at least part of the range. Very wide dynamic speed range can be obtained with armature voltage control. However, below about 60% of base speed, the motor should be derated or used for only short periods. DC... (read more)

  approaches. Amplifier costs for both systems have dropped in recent years, moreover, and are forecast to drop further. Thus, the cost differential between the two approaches is an increasingly smaller percentage of total system cost. The situation has brought a large number of competitors into the market, helping to reduce prices for brushless DC motor BLDC systems. A result is that brushless DC motor sales have risen rapidly in the last few years. And sales of brushless DC motors continue to increase... (read more)

  Coreless DC Motors

  commutator has lower peripheral speed, less wear, and accounts for a smaller motor. Outside-field motors are usually selected for high acceleration. Because of this, the rotor coils must handle a large load torque and dissipate high heat produced by peak currents. To handle the torque, manufacturers strengthen the rotor with glass epoxy. Since the rotor does not have an iron core to act as a heat sink, the housing has ports for forced air cooling. Recent advances in coreless motor design include... (read more)

  and secured as a unit in the armature. Toothless construction provides more space for armature coils and provides higher current ratings. Iron losses are cut by 50%, and armature inductance approaches that for cup motors. Toothless motors do not cog at low speed. And because coil insertion is easier, motor diameters can be smaller. In toothless motors that use ceramic magnets, flux density in the air gap is much lower than in conventional motors. The low density results from the large air gap... (read more)
