Powershell to get instance name

Question

Hi,
Not sure whether this is the forum to ask.I have a list of servers names and i need to get the instance names in below format.
SERVERNAME\INSTANCE1
The o/p of the script actually shows Servername,MSSQL$Instance name..Anyway to tweak this to SERVERNAME\INSTANCE1?
$servers = get-content "C:\SQLCheck\machinelist.txt"
$logfile = "C:\SQLCheck\sql-instances.txt"
$logerrs = "C:\SQLCheck\sql-failures.txt"
Echo "Server, Instance" >> $logfile
ForEach ($server in $servers) {
$instances = Get-WmiObject -ComputerName $server win32_service | where {$_.name -like "MSSQL*"}
if (!$?) {
Echo "$server - No SQL instance found" >> $logerrs
Echo "$server - No SQL instance found"
Else {
ForEach ($instance in $instances) {
if (($instance.name -eq "MSSQLSERVER") -or ($instance.name -like "MSSQL$*")) {
Echo "$server\$instance.name" >> $logfile
Echo "$server, $($instance.name)"
