HYBRID STEPPER

A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates indiscrete step increments when electrical command pulses are applied to it in the proper sequence. The motors rotation has several direct relationships to these applied input pulses. The sequence of the applied pulses is directly related to the direction of motor shafts rotation. The speed of the motor shafts rotation is directly related to the frequency of the input pulses and the length of rotation is directly related to the number of input pulses applied. Wide range of Gearboxes also available

brushless motor

BRUSHLESS MOTOR

A brushless DC motor (BLDC) is a synchronous electric motor which is powered by direct-current electricity (DC) and which has an electronically controlled commutation system, instead of a mechanical commutation system based on brushes. In such motors, current and torque, voltage and rpm are linearly related. Wide range of Gearboxes also available

pm_stepping_motor

PM STEPPING MOTOR

Often referred to as a “tin can” or“ can stack” motor the permanent magnet step motor is a low cost and low resolution type motor with typical step angles of 7.5 to 15° (48 – 24steps/revolution) PM motors as the name implies have permanent magnets added to the motor structure. The rotor no longer has teeth as with the VR motor. Instead the rotor is magnetized with alternating north and south poles situated in a straight line parallel to the rotor shaft. These magnetized rotor poles provide an increased magnetic flux intensity and because of this the PM motor exhibits improved torque characteristics when compared with the VR type.

ac servo motor

AC SERVO MOTOR

A Servo Motor is defined as an automatic device that uses an error-correction routine to correct its motion. The term servo can be applied to systems other than a Servo Motor; systems that use a feedback mechanism such as an encoder or other feedback device to control the motion parameters. Typically when the term servo is used it applies to a 'Servo Motor' but is also used as a general control term, meaning that a feedback loop is used to position an item.

news & events STEPPER MOTORS – Unipolar vs. Bipolar

Unipolar – A unipolar driver’s output current direction cannot be changed.
There are two sets of the coils for each phase in a motor.
Only one set of the coils can be energized at a time.
Each coil represents one phase.
Therefore, only 50% of the winding is utilized in the unipolar drive. The number of mechanical phases equals the number of electrical phases.
Due to the fact unipolar drivers only use 50% of the windings, the performance ranges from low to moderate.
The benefit of this is that it doesn’t generate too much heat.

Bipolar – A bipolar driver’s output current direction can be changed. 100% of the winding is utilized in the bipolar drive.
That means the two sets of the coils in each phase can be connected either in series or in parallel to become one set of a coil.
Current direction changed from the driver creates another mechanical phase.
The number of mechanical phases is always twice the number of electrical phases.
Bipolar drivers provide 40% more holding torque than unipolar drivers, but typically run at higher temperatures.
For this reason, proper heat dissipation is important with bipolar drivers.
