What is a high torque starter motor?

High torque starter motors are modern gear reduction units adapted to fit older vehicle applications. Consequently, they run faster and start the engine more easily. They draw about half the current of an original starter putting less strain on the battery and electrical system of the vehicle.

What is the torque of a starter motor?

With a starter pinion to ring gear ratio of 10:1 the motor must be able to produce a maximum stalled torque of 24 Nm and a driving torque of 8 Nm.

What does the S and R mean on a starter?

S is for “start” R(sometimes I) , well, not sure on R, but I is for ignition(points cars used this to bypass the ignition resistor on crank(oil filled coils don’t last long with full 12-14v to them, so the resistor dropped feed voltage will running to ~10v, but they still needed 12+v to start the engine)

What is a PMGR starter?

PMGR starters have no field coils like positive-engagement starters do. This means that power is sent directly to the starter armature through the brushes and commutator, meaning less battery power is wasted energizing the field coils and that less heat is generated by the starter as well.

What is a gear reduction starter?

Gear reduction starters use gears to reduce the speed of a higher-speed electric motor in order to extract more torque at the flywheel end of the starter. Two typical designs are Offset Gear Reduction and Planetary Gear Reduction.

What is full load torque?

The Full-load Torque is the torque required to produce the rated power of an electrical motor at full-load speed. In imperial units the Full-load Torque can be expressed as. T = 5252 Php / nr (1)

How much is a starter at Autozone?

How Much a Starter Replacement Costs. The cost of rebuild parts for a starter can range from as little as $50 to as much as $350. A brand-new starter can range from $80 to over $350. For a qualified mechanic to replace or rebuild your starter, you can expect to pay between $150 and over $1,100.

What does M and B mean on a starter relay?

Typically, a starter-mounted solenoid has three terminals with three connections: The “B” or “battery” terminal: The terminal that connects the solenoid directly to the positive battery cable. The “M” or “motor” terminal: The terminal that attaches to the cable that connects to the starter motor.

What does the S and I stand for on a starter solenoid?

S stands for “start”, not starter. I stands for “ignition”. As explained above when trying to start the car power is put to the s terminal and the solenoid is energized. The other end of the coil is connected thru the mounting bolts.
