## What is the torque of a windshield wiper motor?

thatoneguy. With the worm gear on the motor, sites selling them state anywhere from 30ft-lb to 50 ft-lb of torque at roughly 60-70 RPM.

## How do you calculate torque on a wiper motor?

= Angular velocity x 60 / (2 x 3.14) = 0.98 * 60 / (2 * 3.14) = 9.3 rpm = 10 rpm The required motor torque from calculation is above is 2.55 Nm and required motor speed is 10 rpm. This requirement is easily fulfilled by wiper motor as it can give 5 Nm torque at 65 rpm.

## How much power does a wiper motor need?

Wiper motors will probably not exceed 50 watts (4.2 amps at 12 volts). A 30 amp motor will require 360 watts and probably produce at least 250 watts of mechanical power. An engine cooling fan or cabin heating/cooling fan might approach that power level.

## How many RPM is a wiper motor?

Product Specification

Motor Voltage 12V
Speed (Rpm) 45
Power (Watts or HP) 14
Rated Voltage 13.5 V

## How many amps does a windshield wiper motor pull?

Neither draw more than 2.5 amps at 12 volts on full load. Mine normally takes about 2 amps and runs at around 8 volts.

## How many amps does a windshield wiper motor use?

Wiper motors are used by enthusiasts to power wheel chairs. You might do well to google “wiper motor current draw”. At any rate an average wiper draws 5 amps, rising to 10 to 12 amps under heavy/stall load.

## Are wiper motors AC or DC?

The wiper motor is a DC (direct current) 12V motor that includes a set of gears and a park switch. The park switch allows the motor to stop when wipers are positioned at the bottom of the windshield in their “park’ position.

## What is the maximum rpm of a wiper motor?

Wiper Motor Speed (Approximate)
Power Supply Terminal Speed
12VDC 5Amps High 50 RPM
5VDC 5Amps Low 15 RPM
5VDC 5Amps High 20 RPM

## How much is a wiper motor?

You will pay between \$230 and \$310 for a windshield wiper motor replacement. The cost of labor on this job will be between \$50 and \$70, while the cost of parts should be between \$180 and \$250.

## How do you test a wiper motor with a battery?

step 2 :Testing the Wiper Motor 0:48

1. Turn the key to the on position.
2. Disconnect the wiper motor electrical connector.
3. Connect the test light clamp to the negative battery post, if you have not already done so.
4. Touch the test light probe to the terminal for the yellow wire to test the park function.

## Can you reverse a windshield wiper motor?

Yes you can reverse the motor, they are usually series field motors, so you need to swap either the field windings or the brushes round, but the mechanics may get stuck.

## How much weight can a windshield wiper motor lift?

I believe wiper motors generate about 12-13 ft/lbs of torque, so if you have a small spindle to use instead of a winch, a wiper motor may very well lift a 50lb load…slowly (Cap’n Jack is on to something with using a lighter door).

## What is a high torque motor?

A high torque motor is toroid shaped, like a donut, and thus has a large diameter and short axis. These motors can directly drive the application without additional mechanics, like worm wheels, belts or pulleys. … A conventional servomotor on the other hand, can reach much higher RPM but generates far less torque.
