What is a bipolar stepper motor

What is a bipolar stepper motor?

A bipolar stepper motor is a type of two phase stepper motor that has a single winding per phase. The current in t5he winding of this type of motor needs to be reversed in order to reverse a magnetic pole, thus making the drive control on bipolar stepper motors much more complicated.

Will reversing polarity damage a proximity switch or proximity sensor?

Reversing the polarity on a proximity switch or proximity sensor should not damage it unless there is some kind of massive surge or short circuit at the same moment.

Additional Information

Types of ActuatorsHydraulic
A hydraulic actuator consists of a cylinder or fluid motor that uses hydraulic power to facilitate mechanical operation. The mechanical motion gives an output in terms of linear, rotary or oscillatory motion. Because liquid is nearly incompressible, a hydraulic actuator can exert considerable force, but is limited in acceleration and speed.
The hydraulic cylinder consists of a hollow cylindrical tube along which a piston can slide. The term double acting is used when pressure is applied on each side of the piston. A difference in pressure between the two side of the piston results in motion of piston to either side. The term single acting is used when the fluid pressure is applied to just one side of the piston. The piston can move in only one direction, a spring being frequently used to give the piston a return stroke.

A pneumatic actuator converts energy formed by compressed air at high pressure into either linear or rotary motion. Pneumatic energy is desirable for main engine controls because it can quickly respond in starting and stopping as the power source does not need to be stored in reserve for operation.
Pneumatic actuators enables large forces to be produced from relatively small pressure changes. These forces are often used with valves to move diaphragms and so affect the flow of liquid through the valve.

An electric actuator is powered by a motor that converts electrical energy to mechanical torque. The electrical energy is used to actuate equipment such as multi-turn valves. It is one of the cleanest and most readily available forms of actuator because it does not involve oil.
